Jens Rosing Perhaps Accounts for Polar Bears in Seasons by the Lake

Summary: Jens Rosing perhaps accounts for polar bears in Seasons by the Lake by author Naja Lund Aparico and illustrator Alex Nees, Dial Books, Tue., 17 March 2026.

"God talks to human beings through many vectors: through each other, through organized religion, through the great books of those religions, through wise people, through art and music and literature and poetry, but nowhere with such detail and grace and color and joy as through creation. When we destroy a species, when we destroy a special place, we're diminishing our capacity to sense the divine, understand who God is and what our own potential is." Robert Francis Kennedy Jr., April 19, 2023, Boston Park Plaza Hotel, Back Bay, Boston, Massachusetts.

“And there’s many people out there who want us to move to the next planet already and I’m like, hang on, let’s not give up on this planet yet," William, Prince of Wales, July 31, 2023, Sorted Food food truck, London, England, United Kingdom.

Jens Rosing perhaps accounts for polar bears in Seasons by the Lake by author Naja Lund Aparico and illustrator Alex Nees, Dial Books for Young Readers, Penguin/Random House, Tue., 17 March 2026.

Artist, author, curator, director, filmmaker, stamp-designer, storyteller Jens Christian Rosing (Tue., July 28, 1925-Sat., May 24, 2008) bided in West-Greenlandic Kalaallisut name-bearing Ilulissat, colonial-Danish name-bearing Jakobshavn. He counted among his competencies curriculum contained in the years 1947-1948 at the Akademiet for Fri og Merkantil Kunst ("The Academy of Free and Mercantile Art"). He directed domesticated reindeer into Nuup Kangerlua ("cape/headland fjord") along the Nuuk ("cape") capital-city area and the Itinnera ("valley-its"; itinneq -ra) reindeer-management station until year 1959.

His expertise in Greenland National Museum's curator directorship enabled his excavating and examining the 8 Qilakitsoq ("sky-little of-that which has"; qilak -kit- -soq) mummies 1976 onward.

The Thule (Latin Thūlē; Greek Θούλη) faction of the Eskimo and the Inuit ("the-people"; Inuktitut ["Inuit-like"; ᐃᓄᒃᑎᑐᑦ] ᐃᓄᐃᑦ) peoples biogeographically favored Nuussuaq ("cape-/headland-/point-big/-great/-large"; nuuk -suaq) Peninsula.

It generated such Rosing artistry as line drawings of mummified clothing that he grouped into the watercolors guarded in his year-1986 book The Sky Hangs Low. The picture-book story Seasons by the Lake has reading and sketching books even as Rosing artistic, illustrated publications perhaps helped to head them into everyday happenings. The total writing ideated into Rosing publications involves eight languages of which 13 articles and books in Danish, four books in Greenlandic, one book in English.

Polar bears perhaps journey from coat-of-arms, hunting-film, hunting-scene, illustrated-publication, national-symbol, postage-stamp art by Jens Rosing into Seasons by the Lake: Adventures in Greenland by author Naja Lund Aparico and illustrator Alex Nees.

Polar-bear coat-of-arms kindled 130 postage-stamp designs even as Jens Rosing knew his first as year-1957, Mother-of-the-Sea ocean-goddess Sassuma Arnaa ("the-deep -belonging mother's"; sassuq -uma arnaq -a).

The years 1962, 1966, 1985 and 2007 logged Drum-Dance (Qilaatersorneq ["frame-drum dancer/drummer [qilaat -lersor), The-Boy-and-the-Fox (Nukappiaraq teriannialu [nukappiaraq terianniaq -lu), coat-of-arms, sled-dog (qimmeq qimuttoq) postage-stamp designs. The Danish-colonial administration traditionally meant the polar bear as symbolic manifestation of the Greenland colony even as that motif modernly maintains home-rule and official Denmark-to-Greenland matters. Polar bears (Ursus maritimus ["bear sea-pertaining"; ursus mare -timus], scientifically) nestle into colonial nooks by year 1666 even as they net home-rule niches since year 1985.

The polar bear occupies northernmost Greenland even as he/she occurs southerlierly in official art by Jens Rosing and wall art by Alex Nees for Seasons by the Lake by Naja Lund Aparico.

Jens Rosing permanentized 145 works into 305 publications even as he penned 17 books, of which such prolific publishing pertained to, performed as, promoted children's literature.

Such Rosing art as his word-image sculpture quartered such quintessential Rosing as his recorded traditions even as such other quests as Rosing films queued wildlife hunts. Artistic, cinematic, literary renditions realized such recognition as the Danish Writers Association's popular-science prize in year 1979 and Greenland Home Rule's culture prize in year 1985. They secured the Danish State Art Foundation's lifelong grant in year 1989 and sequenced into the Greenland Home Rule's Decoration for Meritorious Services in year 1997.

Jens Rosing perhaps transmits such traditions as animal-teeming land- and water-scapes, such treasures as the home-rule polar bear to Seasons by the Lake by author Naja Lund Aparico and illustrator Alex Nees.

Dr Hauer Addresses Connecting and Creating Municipal Forestry Bridges

Summary: Dr Hauer addresses Connecting and Creating Municipal Forestry Bridges with TREE Fund webinar-series hosts Drs Beau Brodbeck and Heath Hupke Nov. 10, 2026.

"God talks to human beings through many vectors: through each other, through organized religion, through the great books of those religions, through wise people, through art and music and literature and poetry, but nowhere with such detail and grace and color and joy as through creation. When we destroy a species, when we destroy a special place, we're diminishing our capacity to sense the divine, understand who God is and what our own potential is." Robert Francis Kennedy Jr., April 19, 2023, Boston Park Plaza Hotel, Back Bay, Boston, Massachusetts.

“And there’s many people out there who want us to move to the next planet already and I’m like, hang on, let’s not give up on this planet yet," William, Prince of Wales, July 31, 2023, Sorted Food food truck, London, England, United Kingdom.

Dr Richard Hauer addresses "Connecting and Creating Municipal Forestry Bridges" with TREE Fund webinar-series hosts Drs Beau Brodbeck and Heath Hupke Nov. 10, 2026.
The webinar presents findings from research funded by a 2021 Bob Skiera Memorial Fund Building Bridges Initiative and John P. White Grant. The grant program honors Robert "Bob" Skiera (1932-July 29, 2005), urban forestry pioneer, past President of ISA International Society of Arboriculture and the Wisconsin Arborist Association, Milwaukee City Forester and member of the Wisconsin Forestry Hall of Fame, and John P. White (April 25, 1957-July 31, 2005), certified consulting arborist, Florida Chapter-ISA’s (FL-ISA) Tree Fund Liaison and Florida Urban Forestry Council (FUFC) Executive Committee member.:

Dr Richard Hauer addresses Connecting and Creating Municipal Forestry Bridges with TREE Fund webinar-series hosts Drs Beau Brodbeck and Heath Hupke Tue., Nov. 10, 2026 at 1:00-2:00 p.m. Eastern Daylight Time (EDT).

Hour-long TREE-Fund webinars begin 5:00 p.m. Greenwich-Mean, 2:00 Atlantic-Daylight, 1:00 Eastern-Daylight, noon Central, 11:00 a.m. Mountain, 10:00 Pacific, 9:00 Alaska, 7:00 Hawaii, 6:00 American-Samoan, 3:00 Chamorro. TREE-Fund webinars conclude at 6:00 p.m. Greenwich-Mean, 3:00 Atlantic-Daylight, 2:00 Eastern-Daylight, 1:00 Central, noon Mountain, 11:00 a.m. Pacific, 10:00 Alaska, 8:00 Hawaii, 7:00 American-Samoa, 4:00 Chamorro. The community and the urban programs that drive community and urban forestry develop designs critical to detailing healthy, resilient, sustainable domiciles of urban and community plants.

Dr Hauer expands upon a bit more than one decade of relevant research even as his data ensue from surveys entailing the years 2014 through 2025.

Community and urban trees furnish their air, land, lifeforms structures with ecological, economic and social benefits even as they fortify the community and the urban infrastructure.

Urban forestry perhaps gathers grouped neighborhoods into city groupings even as such municipal gatherings generalize into the greater area whose generated bridges give us urban forestry. It heeds what has to be done, for what, by whom even as it heralds the forestry trio of tree planting, tree pruning and tree removal. It impels investigating the tree species ideal for and important to impeding air, land and water pollution; impermeable surfaces; seesaw-soil moisture; stormwater runoff; urban-heat island effects.

Dr Hauer journeys through Connecting and Creating Municipal Forestry Bridges with TREE Fund webinar-series Drs Brodbeck, Hupke, Rowe even as ecological, economic, social judgments and justifications sometimes jeopardize, often join such junctures.

Municipal budgets kindle different calculations and categories even as the city, the community, the urban size keeps such survey ranges as 2,500 to 1,000,000-plus known inhabitants.

Such budgets list like, unlike community, municipal, urban forestry-linked expenses, positions, responsibilities, schedules, values even as they log like, unlike tree-generalist, tree-specialist and woody-plant species labels. International Society of Arboriculture-Certified Arborists, perhaps ISA-Certified Master Arborists, Tree-Worker Aerial-Lift and Climber Specialists, Urban-Forest Professionals, Utility Specialists manifest among the positions that municipal budgets mention. Such skilled, special-trained volunteers as Cooperative-Extension Master Gardeners and Advanced-Master Gardener Tree Stewards perhaps nestle into municipal budgets even as lesser- and greater-populated neighborhoods note them.

Dr Hauer observes 10-plus years of Connecting and Creating Municipal Forestry Bridges with TREE Fund webinar-series Drs Brodbeck, Hupke and Rowe even as municipal budgets increasingly occasion, opportunize and optimize tree-species diversity.

Tree-species diversity promotes 3-30-300 prescriptions of perceiving minimally 3 trees from every home, 30% tree-canopy cover in every neighborhood, public greenspaces within 300 meters (984.252 feet).

Community, municipal, urban forests queue impermeable buildings, gas pumps, parking lots, parking spaces, pavement, sewage systems, traffic lanes even as such quarters quarrel with green infrastructure. They require such specialized reinforcement and remediation that company and municipal budgets reveal routines realizable by permanent staff and responsibilities rendered by contracted, non-payroll, temporary hiring. The bridges that secure community, landscape, municipal, neighborhood, suburban, urban forestry suggest private and public, street and urban trees sequenced in overlapping series of 3-30-300 woodies.

Dr Hauer teams professional training and species diversity in Connecting and Creating Municipal Forestry Bridges with TREE Fund webinar-series Drs Brodbeck, Hupke and Rowe even as 10-plus-year surveys trend tree-specialized, tree-specied talents.
