Hyla versicolor is a New World frog native to eastern North America.

The small, tailless amphibian claims homelands in southeastern Canada from Manitoba through Ontario and Quebec. A disjunct, or separate, population is found in New Brunswick.

In the eastern United States, Hyla versicolor has a wide geographic range sweeping from the Great Plains eastward to the Atlantic coast.

Hyla versicolor is known commonly in English as common gray treefrog, Eastern gray treefrog, North American treefrog or tetraploid gray treefrog.

Eastern Gray Treefrogs enjoy arboreal (Latin: arbor, “tree”) habitats, such as forested areas, rural landscapes, and woodland ponds. During the breeding season they favor proximity to shallow water ecosystems, such as roadside ditches, swamps and vernal (Latin: ver, “spring”) pools.

Eastern Gray Treefrogs measure around 0.5 to 0.7 inches (13 to 20 millimeters) as newly transformed froglets. As adults, they maximize at lengths of around 1.25 to 2.5 inches (32 to 62 millimeters).

The dorsal, or back, of Eastern Gray Treefrogs presents a warty appearance. Eastern Gray Treefrogs reveal a dark patterning on their backs and express a mottled coloration range of gray or white to brown or green as a camouflaging response to their environment.

Bright orange-to-yellow coloring splashes across the ventral surface, or underside, of Eastern Gray Treefrogs’ hind legs. The bright flashes, which are exposed strategically during leaps, tend to startle predators.

Eastern Gray Treefrogs display slight sexual dimorphism (Ancient Greek: δίς, dís, “twice” + μορφή, morphḗ, “form, shape” + -ισμός, -ismós, suffix forming abstract nouns). Males are smaller than females. Males have vocal sacs for calling during mating season and darkened throats while females have light throats and do not vocalize.

Eastern Gray Treefrogs are virtually indistinguishable physically from Cope’s Gray Treefrog (Hyla chrysoscelis), also known as Southern Gray Treefrogs. Enjoying a great native range, Cope’s Gray Treefrogs spill over from homelands shared with their lookalikes southward deep into peninsular Florida and westward deep into the Great Plains.

Males of the two lookalike species may be identified audially by notes per second in their mating calls. Eastern Gray Treefrogs trill about 17 to 35 notes per second whereas Cope’s Gray Treefrogs speed at higher pitched trills of 35 to 70 notes per second.

The lookalikes may also be distinguished microscopically by chromosome tally. Hyla versicolor’s common name of Tetraploid (Ancient Greek: τέσσαρες, téssares, “four” + εἶδος, eîdos, “form, likeness”) Gray Treefrog reflects its possession of four sets of chromosomes, for a total of 48. As diploids (Ancient Greek: διπλοῦς, diploûs, “double”+ εἶδος, eîdos, “form, likeness”), Cope’s Gray Treefrogs retain two sets, for a total of 24.

Over the Memorial Day weekend, as I approached my house’s downstairs back door from the yard’s eastern, ephemeral creek border, I noticed a curved outline protruding above the southern edge of the top of the doorframe. My guest was an Eastern Gray Treefrog, hunkered down in a great, predatory location only inches away from the outside light, a favorite gathering spot for insects.

A nudging with the golden brown wooden handle of my garden rake induced the frog to jump onto the sturdy tool. As I lowered the rake, the frog jumped onto the concrete stoop and immediately discolored from light green to dull gray.

As my visitor’s home probably was sited either in the willow (Salix spp.) grove on the creek’s south banks or along the vernal pool slightly east of the grove, I nudged him into a tin pail and transported him to the south bank. Pausing slightly, my froggy guest traced a graceful arc in his leap across the creek and into the underbrush.

Sallie Ann Jarrett: Brave Dog Mascot of 11th Pennsylvania Infantry

Summary: Sallie Ann Jarrett, a brindle American Staffordshire Terrier, was 11th Pennsylvania Infantry's mascot. The 11th's Gettysburg monument includes her statue.

Confederate and Union soldiers eased challenges -- ranging from the boredom of camp life to the terrors of battlefields -- of the War Between the States (April 12, 1861–May 9, 1895), also known as the American Civil War, by incorporating animals as pets into the rigors of military life and by designating animals as their regimental mascots.

Animal mascots and pets inspired their regiments with their courage, loyalty and stamina.

A diversity of animals served as regimental mascots and pets, including: bear, dogs, camel, donkey and raccoons.

The 11th Pennsylvania Volunteer Infantry, active from April 26, 1881, to July 1, 1865, numbers among regiments featuring a canine mascot.

From May 4 to May 27, the recently recruited regiment, under the command of Colonel Phaon Jarrett (Feb. 9, 1809–Sept. 10, 1876), was assigned to Camp Wayne. The infantry training ground was located near West Chester, in southeastern Pennsylvania.

A brindle American Staffordshire Terrier endeared herself to the regiment as a four-week old spring puppy gifted in May 1861 by a resident of West Chester.

The regiment named the pup Sallie Ann Jarrett to honor both a West Chester belle and the 11th’s first colonel, Phaon Jarrett.

Also known as Amstaff, the medium-sized American dog breed belongs to the dog type commonly known as pit bulls, bred to combine bulldog strength with terrier agility.

Amstaff presents a stocky outline and moves with a springy gait. High-set ears, muscular build, and well-arched feet contribute to alert, strong, and agile grace.

American Staffordshire Terriers model a range of coat colors, including brindle, an attractive brown or tawny streaked with other colors.

Sallie Ann became an integral part of her regiment by learning bugle calls and drum rolls. She participated in dress parades, drills and marches. Sallie Ann positioned herself at front lines on battlefields. She also ventured onto battlefield to guard the regiment’s wounded and dead.

Steadfastly participating in all regimental campaigns, Sallie accompanied her regiment to Gettysburg, in southeastern Pennsylvania, where the war’s bloodiest battle raged from July 1 to July 3, 1863. On the first day, Sallie Ann became separated from her regiment during the massive retreat of Union forces from positions in the west and north to Cemetery Hill in the borough's southeast. Noting her absence, her regiment despaired that she had perished.

At the end of the bloody battle, Sallie Ann was discovered guarding fallen companions on Oak Ridge, the site of original defense by her regiment, located southwest of Harrisburg Road, the northeastern entry into Gettysburg.

As a fearless canine soldier, Sallie Ann finally was felled on the front line Feb. 6, 1865, during the Battle of Hatcher’s Run by a bullet piercing her brain. The battle, fought from Feb. 5 to 7, was launched as part of Union forces’ Richmond-Petersburg Campaign (June 9, 1864–March 25, 1865) to sever Confederate supply lines.

Five days after the battle, a member of the regiment recorded that fellow soldiers on the front line, despite enduring “a murderous fire,” ceased fighting long enough to bury their beloved mascot on the spot where she was felled.

Less than two months later, the War Between the States officially ended with the issuance of a proclamation Tuesday, May 9, by 17th U.S. President Andrew Johnson (Dec. 29, 1808-July 31, 1875).

The regimental monument dedicated Sept. 3, 1890, by veterans of Sallie Ann’s regiment at Gettysburg includes a life-size bronze likeness of 11th Pennsylvania Volunteer Infantry’s beloved, brave mascot on a granite pedestal in a place of honor at the monument’s front.

The bronze statues of an infantry soldier and of Sallie were created by sculptor Edward A. Kretschman (Aug. 27, 1847-ca. 1923). The statues were cast by Bureau Brothers Foundry of Philadelphia.

The monument is sited on Oak Ridge, where Sallie Ann had comforted and watched over dead and dying members of her regiment throughout the three days of the Battle of Gettysburg.

Kiwa tyleri: Antarctic Yeti Crab Known Commonly as The Hoff

Summary: Kiwa tyleri is a yeti crab, a newly discovered family of deep-sea crabs. Found near Antarctica, Kiwa tyleri is named The Hoff after actor David Hasselhoff.

Dense communities of Kiwa tyleri congregate at E9 chimney, southern branch of East Scotia Ridge, at depth of around 7874 feet (2400 meters): Alex D. Rogers et al., CC BY 2.5, via Wikimedia Commons

Kiwa tyleri is the third species in a new family of deep-sea crabs discovered in the 21st century.

The genus name, Kiwa, and the family name, Kiwaidae, honor a Polynesian goddess of crustaceans.

The first species, Kiwa hirsuta (Latin: hirsuta, “hairy, shaggy”), was discovered in March 2005 on the periphery of the Pacific-Antarctic Ridge’s deep-sea hydrothermal vents in the southeastern Pacific.

The second species, Kiwa puravida, was discovered in 2006 at a deep-sea cold seep, or vent, off Costa Rica.

Kiwa tyleri, namesake of British deep-sea and polar biologist Professor Paul Tyler of England's University of Southampton, was discovered in January and February 2010 at depths of 7874 to 8530 feet (2400 to 2600 meters) in the East Scotia Ridge in the South Atlantic and Southern oceans between South Georgia and the South Sandwich Islands.

The Kiwaidae are placed, along with two other families (Chirostylidae, Eumunididae), in the Chirostylidea, one of two superfamilies of squat lobsters.

Although superficially similar to true lobsters (Homaridae, Nephropidae families), squat lobsters feature dorsoventral (back to belly) flattening and hold their fifth pair of appendages curled under their thorax.

According to DNA sequence data, Kiwaidae’s superfamily is related more closely to the Hippoidea superfamily of mole crabs and the Paguoidea superfamily of hermit and king crabs. Kiwaidae's superfamily is related more distantly to the Galatheoidea superfamily, which consists of one family of porcelain crabs and three families of squat lobsters.

With their prominent feature of a furry appearance produced by dense coverings of bristles, known as setae (Latin: seta, "bristle"), on their appendages, Kiwa crabs are known commonly in English as yeti crabs, after the Himalayas' legendary Abominable Snowman, known as Yeti (Nepali: himamānav, "mountain man").

Kiwa tyleri’s common name of The Hoff honors actor, musician, and producer David Hasselhoff (born July 17, 1952), famed as hairy-chested actor and producer of action drama television series, Baywatch.

The Hoff thrives in the highly restricted habitat of geothermally heated hydrothermal vents. Steep temperature changes reach a maximum outflow temperature of 716 degrees Fahrenheit (380.2 degrees Celsius).

Communities cluster in high densities of over 700 individuals per square meter at two isolated sites, as the frigid temperatures of the surrounding polar waters, registering at about 32 to 29 degrees F (0.0 to minus 1.3 degrees C), preclude migration.

Only brooding females venture away from the adult refuge of vent chimneys to release larvae into the cold temperatures required for larval survival.

Kiwa tyleri individuals surmount the low-food debit of the deep-sea polar environment by feasting on dense bacterial mats that carpet vent chimneys.

Kiwa tyleri has a ghostly white appearance and features a bare carapace (French: carapace, "tortoise shell”; Portuguese: carapaça, "shell"), which is the upper, or dorsal, section of their exoskeleton, or shell.

Thick fields of bristles on its ventral, or belly, side -- which inspired the nickname of The Hoff by its discoverers -- facilitate harvesting bacterial mats from chimney vents for large-scale harboring on its own body as a ready-to-eat food source.

The Kiwa tyleri species exemplifies the astounding ability of wildlife to thrive even in seemingly unforgiving ecosystems.

As a newly discovered species also requiring the establishment of a new family, Kiwa tyleri reveals that human knowledge equates to drops in buckets, with the excitement of discovery an ever-present challenge as well as an unexpected gift.

Undulatus Asperatus: Newly Discovered Cloud Reminiscent of Choppy Seas

Summary: Undulatus Asperatus, a newly discovered cloud formation, may be the first addition to the International Cloud Atlas since 1951's cirrus intortus.

Jane Wiggins' photo that started movement for recognition of undulatus aspseratus, the people's cloud, as new cloud type: USA Today Weather @ usatodayweather via Twitter June 22, 2015

Clouds are one of the most familiar, obvious and prevalent of the natural phenomena found within the boundaries of Earth, the Blue Planet that orbits as the third planet around the sun. Meteorologists, scientists who study the atmosphere, define a cloud as an atmospheric suspension of a visible mass of condensed or crystallized droplets of water above the surface of a planetary body.

The etymology of the word "cloud" harkens back to the Old English word clud, meaning "mass of rock." By the 12th century, during the High Middle Ages (11th to 13th centuries), the definition of clud had expanded metaphorically, due to perceived similarities between cumulus (Latin for "heap, mass") clouds and rock masses, to supplant the Old English word weolcan as the designation for the sky's water-based formations. The study of clouds, as a branch of meteorology, is known as nephology (Ancient Greek: νέφος, néphos, “cloud” + λόγος, lógos, “explanation”).

Most clouds and almost all weather occur in the troposphere, the lowest layer of Earth's atmosphere. The troposphere extends its bottom at the Earth's surface upward to its top, which varies in height according to latitude and season.

The troposphere generally exhibits an extension of 33,000 feet (10 kilometers; or 6.2 miles) upward from sea level. The troposphere measures its low of 23,000 feet (7 kilometers; or 4 miles) at polar latitudes in winter. Its high of 65,000 feet (20 kilometers; or, 12 miles) occurs near the equator in summer.

Cloud names reflect such characteristics as their height in the sky and their appearance, or texture.

Low-altitude clouds, which occur below 6,500 feet (1.98 kilometers), feature cumulo-/-cumulus (Latin: cumulus, "pile, heap") and/or strato-/-stratus (Latin: stratus, "spreading, layer") in their names.

Mid-altitude clouds, which occur between 6,500 feet (1.98 kilometers) and 20,000 feet (6 kilometers), are named with alto- (Latin: altus, "high, lofty") as prefix.

High-altitude clouds, which occur above about 20,000 feet (6 kilometers), are distinguished by names with cirro- (Latin: cirrus, "curl") as prefix.

Cloud classification consists of 10 basic genera by altitude of occurrence.

The world of clouds is documented in The International Cloud Atlas, first published in 1896 by the International Meteorological Organization and continued by its successor, the World Meteorological Organization. The WMO is an intergovernmental organization of the United Nations based in Geneva, in western Switzerland.

The most recent edition of the atlas was published in 1975. The last instance of a new entry recognizing a newly discovered cloud formation occurred in 1951 with the addition of cirrus intortus (Latin: cirrus, "curl" + intortus, "twisted, wound") to the cloud roster.

A recent cloud discovery may trigger and grace a new edition of the atlas. Undulatus asperatus (Latin: undulatus, "undulated, wavy" + intortus, "agitated, roughened") is currently under assessment by the WMO, with acceptance deemed to occur in 2015. Undulatus asperatus clouds appear to straddle low to middle altitudes, being found above and below 6,000 feet.

On June 20, 2006, Jane Wiggins, a paralegal who is an amateur photographer in east central Iowa, photographed low clouds, undulating with dark and light shadows against a green-yellow backdrop over downtown Cedar Rapids. Within 15 minutes of her photograph, the dramatic, massive formation dissipated.

Other images from around the globe joined Jane's searing image to inspire Gavin Pretor-Pinney, founder of the Cloud Appreciation Society and author of The Cloudspotter's Guide (2006), to name the formation and to seek official classification. Gavin's name choice of undulatus asperatus reflects the cloud's reminiscence of choppy seas. Gavin's nickname for the startling cloud is the Jacques Cousteau cloud, in honor of legendary underseas explorer Jacques-Yves Cousteau (June 11, 1910-June 25, 1997).

Although a rare phenomenon with only recent documentation, undulatus asperatus clouds are not necessarily emblematic of underlying conditions, such as climate change. Gavin credits the recent awareness of the unusual formation's existence to easy availability of a plethora of portable, high-quality photographic devices in the technologically savvy 21st century. Despite their sometimes menacing, spectacular appearance, undulatus asperatus clouds do not function as storm harbingers.

According to research conducted by Graeme Anderson for his 2010 dissertation in the Department of Meteorology at the University of Reading in south east England, undulatus asperatus clouds seem to form in the conditions that produce mammatus (Latin: mamma, "breast, udder") clouds. Mammatus clouds, also known as mammatocumulus, are characterized by puffy, smooth pouches hanging from a cloud base and are formed in environments of moisture, sharp temperature gradients and wind shear (difference in wind direction and speed).

As with mammatus clouds, the WMO may view undulatus asperatus as a cloud supplementary feature.

Whatever the official outcome, the photographs of undulatus asperatus and the ensuing information gathering serve as inspiring spotlights on the dedication and efficacy of citizen science, also known as crowd-sourced science, which refers to contributions to science made by the general public.

Undulatus asperatus shines as the people's cloud.

Virginia Independent Cities: US Rarity With Three Outside of Virginia

Summary: Virginia independent cities number 38 in 2015, accounting for 95% of US total of 41. Only three are outside of Virginia: Baltimore, Carson City, St. Louis.

An independent city constitutes a primary form of local government below the state level. An independent city is a governmental entity responsible for its own administration. An independent city incorporates as a jurisdictional unit that, despite geographic proximity, is separate and distinct from any counties.

The number of independent cities in the United States currently totals 41. Thirty-eight are located in the Commonwealth of Virginia.

Three independent cities are located outside of Virginia: Baltimore, Maryland; Carson City, Nevada; and St. Louis, Missouri.

Of this non-Virginia trio, Baltimore is the largest in population, with a 2014 U.S. Census Bureau estimate at 622,793, but is the second largest in size, estimated at 80.94 square miles in 2010.

St. Louis is the second largest in population, with a 2014 estimate of 318,416, but is the smallest in size, estimated at 61.91 square miles in 2010.

Carson City has the smallest population of the trio, with a 2014 U.S. Census Bureau estimated population of 54,522, but has the largest size, estimated at 144.66 square miles in 2010.

Virginia’s independent cities, which numbered 41 by the late 20th century, total 38 in 2015.

Three independent cities relinquished their unique status and reverted to town status to rejoin the counties in which they are sited. In 1995, South Boston in the commonwealth’s south central region rejoined Halifax County. In 2001, Clifton Forge in the southwest rejoined Alleghany County. In 2013, Bedford, also in the southwest, rejoined Bedford County.

Located on the Atlantic Ocean in America’s First Region in the southeast, Virginia Beach is the independent city with the largest population, estimated in 2014 at 450,980, and also is the commonwealth’s most populous city.

Located in the Appalachians of southwestern Virginia, Norton ranks as the least populous independent city, estimated in 2014 at 4,031.

Located on the Great Dismal Swamp shared by southeastern Virginia and northeastern North Carolina, Suffolk encompasses the largest area, estimated in 2010 at 400.17 square miles. Drained by two watersheds, Cameron Run and Four Mile Run, in Northern Virginia, Falls Church represents the smallest area, estimated in 2010 at 2.0 square miles.

From the commonwealth’s first incorporated city of Williamsburg in 1722 to cosmopolitan Richmond in 1842 and peninsular Poquoson (pəˈkoʊsən) in 1975, Virginia’s independent cities present a fascinating array of history and landscapes. Checking each unique independent city off a list of must-see places is one of many rewarding ways to organize sightseeing and travel in the Old Dominion.

Martian New Year and Summer Solstice 2015: Happy New Year From Mars

Summary: The Martian New Year on June 18, coincides with Mars' northern hemisphere spring equinox and happens three days before Earth's 2015 summer solstice.

As the fourth planet from the Sun and the second smallest planet, after Mercury, in the Solar System, Mars requires the equivalent of about 687 Earth days to complete its orbit around the Sun. One Martian year equals 1.8809 Earth years, or 1 year 320 days 18.2 hours.

The Red Planet’s New Year coincides with an important Martian seasonal event, its northern hemisphere spring equinox. Reckoning of the Martian New Year started with the assignment of the Northern spring equinox of April 11, 1955, as Year One. According to this system, 2015 rings in Martian Year 33.

In 2015, the Martian New Year falls on Thursday, June 18, which occurs three days prior to an important terrestrial seasonal event, the Northern Hemisphere's summer solstice.

A solstice (Latin: solstitium, “sun standing still”; from sol, “sun” + sistere, “to stop, to make stand still”) signifies the southernmost or northernmost latitude of distance away from the equator at which the sun appears directly overhead.

In the Northern Hemisphere the sun’s zenith, or highest point in the sky, occurs in June. The maximum tilting of the North Pole, at about 23.5 degrees toward the sun, takes place over the Tropic of Cancer, presently at 23°26’14.2” north latitude.

In the Southern Hemisphere the sun’s zenith occurs in December. The maximum tilting of the North Pole, at about minus 23.5 degrees away from the sun, takes place over the Tropic of Capricorn, presently at 23°26’14.2” south latitude.

The date for the northern summer solstice, which occurs oppositely as the winter solstice in the Southern Hemisphere, varies annually between June 20 and June 22. In 2015, the northern summer solstice takes place Sunday, June 21, at 16:38 Coordinated Universal Time (12:38 p.m. Eastern Daylight Time in North America).

The National Aeronautics and Space Administration (NASA), which currently is focusing on capabilities for launching a manned mission to Mars by the 2030s, is celebrating Mars Year 33 with a three day extravaganza of science, technology, engineering, arts and mathematics (STEAM) activities from Friday, June 19, through Sunday, June 21, at coordinates 40.6967 degrees north 80.0122 degrees west in downtown Mars, Pennsylvania.
On March 6, 1895, Mars was incorporated as a borough in southern Butler County in the Keystone State’s west central region. The origin of the borough’s unusual name is unclear.

A popular year-round roadside attraction in Mars is a replica of a spaceship in the town park at the intersection of Grand Avenue and Pittsburgh Street, across from Mars National Bank. The small park also features the bell from the USS Mars (AFS-1), the borough's namesake laid down May 5, 1962, as one of seven Mars-class combat stores ships. On July 15, 2006, USS Mars was sunk about 54 nautical miles (62 miles; 100 kilometers) off the coast of Oahu as a Sink Exercise (SINKEX) target during the Rim of the Pacific Exercise. Held biannually since 1971, RIMPAC is the world's largest international maritime exercise.

Future New Year dates for Mars include Friday, May 5, 2017; Saturday, March 23, 2019; and Sunday, Feb. 7, 2021.

Moyenne Island: Brendon Grimshaw’s Paradise Enjoyed as National Park

Summary: Moyenne Island, a private Indian Ocean islet transformed into a nature reserve by Brendon Grimshaw, now is part of Ste Anne National Park in the Seychelles.

As a small island of about 22 acres (9 hectares), Moyenne Island lies off the northeastern coast of Mahé, largest island of the Seychelles. The 115-island archipelago known as the Seychelles is located in the southwestern Indian Ocean. The archipelago has held the status of independent republic in the Commonwealth of Nations since 1976.

Sited midway between Sainte Anne Island and Long Island, Moyenne Island is about 3.7 miles (6.0 kilometers) east of Victoria, main city and port of Mahé and also capital of the Seychelles. With Africa as closest continent to the Seychelles, the Port of Victoria is about 974 nautical miles (1,120.8 miles; 1,803.8 kilometers) east of Kenya’s port city of Mombasa.

Owners of Moyenne Island are listed on a plaque in the islet’s little, open-air chapel.

The first known owners of Moyenne Island were Melidor Louange and Julie Chiffon, who moved to the rustic paradise in 1850 and lived there for 42 years before selling in 1892 to Alfred d’Emmerez de Charmoy.

In the 20th century, Emma Wardlow-Best, who acquired ownership in 1899, enjoyed the island as a sanctuary for stray dogs that she rescued from nearby Mahé until her death around 1913.

Lying basically vacant for almost five decades, Moyenne Island yielded to nature, primarily in the form of bushes. The overgrown islet became so thick with bushes that ripe coconuts never reached the ground.

In 1962, ownership passed to Brendon Grimshaw (ca. 1926–July 2012), who purchased Moyenne Island on the last day of his three-week search in the Seychelles, from Philippe Georges, who had inherited the uninhabited island from his godfather. At first uninterested in selling, Philippe Georges perceived that Brendon would take care of the island and sold Moyenne for £8,000 ($5,036 in 1962).

Born in the West Yorkshire town of Dewsbury (Old English: dēaw, “dew" + beorg, "hill") in north central England, Brendon left school at age 15 to begin a newspaper career. Recognized as England’s youngest newspaper editor, Brendon followed his dream by becoming editor of African newspapers in Kenya and Tanzania.

Through his prestige as editor, Brendon befriended everyday as well as powerful people.

The assassination of his book-loving good friend, Eduardo Chivambo Mondlane (June 20, 1920–Feb. 3, 1969), an anthropology/sociology professor and Mozambique independence activist, by a book bomb signaled, for Brendon, the end of his time in Africa. He sensed that the conflicts between colonialism and independence endangered anyone with human concerns.

By 1973, having extracted himself from his active life as a newspaperman, Brendon settled permanently on Moyenne Island.

Describing himself as a “very ordinary guy,” Brendon perceived his new role as guardian of Moyenne Island. Brendon listened to the island in determining projects for his new home. He felt that the island made clear to him the sequence of clearing bush and encouraging endemic fauna and flora.

He and his assistant, Rene Lafortune (died 2007), son of the fisherman who had served as island guardian for the previous owner, first cleared ubiquitous thickets of shrubs in order to make a path to see what the islet actually looked like. It took them two years to complete the main path. Moyenne Island now features 2.9 miles (4.8 kilometers) of nature paths.

In creating an attractive, useful nature reserve, Brendon and Rene tackled the absence of birds and of trees, except for coconut palms. In the first year, they experimented by planting 50 mahogany trees (Swietenia spp.). The next year, because Brendon and Rene perceived that the trees loved their new home, they planted 150 more. Subsequent plantings brought the total to 700 mahoganies. The trees soar to 60 to 70 feet (18 to 21 meters).

Faunal and floral transformations effected by more than three decades of listening to the island include over 2,000 birds; over 2,000 coconut palms; and over 16,000 trees.

A special attraction is the 100-plus population of free-roaming giant tortoises. Aldabra Atoll giant tortoises (Aldabrachelys gigantean) are native to their namesake insular home, the isolated, uninhabited Aldabra Atoll. Located in the Outer Islands of the Seychelles, Aldabra is the world’s second largest coral atoll.

Aldabra tortoises join Galápagos giant tortoises (Chelonoidis nigra) as the only two extant, or still existing, groups of insular giant tortoises in the world. Both are classified as vulnerable species.

On Sept. 28, 1998, septuagenarian (Latin: septuagenarius, "containing 70") Brendon founded the Moyenne Island Foundation as a non-profit organization. The foundation is responsible for overall management of Brendon's nature reserve in line with preservation guidelines. Moyenne Island Foundation acquires ownership of the private island after Brendon's death, which he often joked as caused by a falling coconut hitting his head.

Despite offers in the millions of pounds for purchase of his paradise, Brendon held to his dream of preserving his paradise for future generations of Seychellois and worldwide nature lovers as a nature reserve rather than as a private resort for wealthy jet-setters.

In 2008, the octogenarian’s dream was realized with inclusion of Moyenne Island into the Sainte Anne Marine National Park, created in 1973 for wildlife preservation. In addition to Moyenne, the Marine Park comprises five other islands: Sainte Anne, Cerf, Île Cachée, Long, and Round.

Visits to Moyenne Island are available as day trips. No overnight accommodations are provided. Camping is not allowed.

In addition to nature walks, snorkeling, swimming, species-rich viewing and outstanding vistas, Moyenne Island includes the mystique of rock-hewn graves for two unknown pirates. Pirate graves are framed by grave sites for Brendon and for his father Raymond (1894–Feb. 1, 1987), who relocated to his son's islet as a widower in 1981.

Moyenne Island exemplifies the perfect harmony of the animal, mineral and vegetable states. The wildlife haven is a must-see destination that serves as a serene tribute to the outstanding, patient accomplishments of Brendon Grimshaw, an extraordinary, ordinary person.
