Urban Park
An urban park or metropolitan park, also known as a municipal park (North America) or a public park, public open space, or municipal gardens ( UK), is a park in cities and other incorporated places that offer recreation and green space to residents of, and visitors to, the municipality. The design, operation, and maintenance is usually done by government agencies, typically on the local level, but may occasionally be contracted out to a park conservancy, "friends of" group, or private sector company. Common features of municipal parks include playgrounds, gardens, hiking, running and fitness trails or paths, bridle paths, sports fields and courts, public restrooms, boat ramps, and/or picnic facilities, depending on the budget and natural features available. Park advocates claim that having parks near urban residents, including within a 10-minute walk, provide multiple benefits.

Gray Catbird
The gray catbird (''Dumetella carolinensis''), also spelled grey catbird, is a medium-sized North American and Central American perching bird of the mimid family. It is the only member of the "catbird" genus ''Dumetella''. Like the black catbird (''Melanoptila glabrirostris''), it is among the basal lineages of the Mimidae, probably a closer relative of the Caribbean thrasher and trembler assemblage than of the mockingbirds and ''Toxostoma'' thrashers. In some areas it is known as the slate-colored mockingbird. Taxonomy The name ''Dumetella'' is based upon the Latin term ''dūmus'' ("thorny thicket"; it thus means approximately "small thornbush-dweller" or "small bird of the thornbushes". It refers to the species' habit of singing when hidden in undergrowth. The specific name ''carolinensis'' is New Latin for "from the Carolinas". The species was first described by Carl Linnaeus in his 1766 edition of ''Systema naturae''. His original name ''Muscicapa carolinensis'' reflected ...

White-breasted Nuthatch
The white-breasted nuthatch (''Sitta carolinensis'') is a species of bird in the nuthatch family Sittidae. It is a medium-sized nuthatch, measuring approximately in length.

Common Duckweed
''Lemna minor'', the common duckweed or lesser duckweed, is a species of aquatic freshwater plant in the subfamily Lemnoideae of the arum family Araceae. ''L. minor'' is used as animal fodder, bioremediator, for wastewater nutrient recovery, and other applications. Description ''Lemna minor'' is a floating freshwater aquatic plant, with one, two, three or four leaves each having a single root hanging in the water. As more leaves grow, the plants divide and become separate individuals. The root is 1–2 cm long. Leaves are oval, 1–8 mm long and 0.6–5 mm broad, light green, with three (rarely five) veins and small air spaces to assist flotation. It reproduces mainly vegetatively by division. Flowers are rarely produced and measure about 1 mm in diameter, with a cup-shaped membranous scale containing a single ovule and two stamens. The seed is 1 mm long, ribbed with 8-15 ribs. Birds are important in dispersing ''L. minor'' to new sites. The sticky ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Salix geyeriana'' is a species of willow known by the common names Geyer's willow, Geyer willow and silver willow.

Northern Riverine Forest
The northern riverine forest is a type of forest ecology most dominant along waterways in the northeastern and north-central United States and bordering areas of Canada. Key species include willow, elm, American sycamore, painted trillium, goldthread, common wood-sorrel, pink lady's-slipper, wild sarsaparilla, and cottonwood. One of the distinct ecosystems is the Riverine Forest. These are found on the lower flood plains along the rivers edge. The main species found here is one of the deciduous species; the Balsam Poplar. These trees like a high volume of moisture and are able to tolerate flooding. They are distinguishable by their thick, gnarly bark and their larger, pointed leaves. These leaves have a distinct drip tip. The trees supply homes for the many native species of fauna. Other Key trees include yellow birch, white birch, sugar maple, American beech, eastern hemlock, white pine, red pine, northern red oak, pin cherry, and red spruce. Key shrubs include striped maple a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Populus Balsamifera
''Populus balsamifera'', commonly called balsam poplar, bam, bamtree, eastern balsam-poplar, hackmatack, tacamahac poplar, tacamahaca, is a tree species in the balsam poplar species group in the poplar genus, '' Populus.'' The genus name ''Populus'' is from the Latin for poplar, and the specific epithet ''balsamifera'' from Latin for "balsam-bearing". ''Populus balsamifera'' is the northernmost North American hardwood, growing transcontinentally on boreal and montane upland and flood plain sites, and attaining its best development on flood plains. It is a hardy, fast-growing tree which is generally short lived, but some trees as old as 200 years have been found. The tree is known for its strong, sweet fragrance, which emanates from its sticky, resinous buds. The smell has been compared to that of the balsam fir tree. Taxonomy The black cottonwood, ''Populus trichocarpa'', is sometimes considered a subspecies of ''P. balsamifera'' and may lend its common name to this species, a ...

Ducks Unlimited
Ducks Unlimited (DU) is an American nonprofit organization 501(c) dedicated to the conservation of wetlands and associated upland habitats for waterfowl, other wildlife, and people. It has had a membership of around 700,000 since January 2013.

Membership included such people as Arthur Bartley and Nash Buckingham, who would later be involved in the conservation movement. In 1930, Joseph P. Knapp, a publishing tycoon who successfully obtained such notable publications as ''The Associated Sunday Magazine'', Crowell Publishing Company, ''Collier’s Weekly'', ''Farm and Fireside,'' and the book publisher P.F. Collier & Sons, founded More Game Birds in America and American Wild Fowlers was quickly absorbed into the new organization.
