ハクトウワシ

アメリカの国鳥であり保全の成功を象徴するハクトウワシは翼開長が最大2.4 mに達し、北米全域の水辺近くの森林や湿地に生息する。強力な空中捕食者兼腐肉食者で魚を主食とするが、水鳥や腐肉も捕食する。DDT汚染と狩猟によって1960年代にほぼ絶滅に瀕したが、農薬の使用禁止と絶滅危惧種法の施行により劇的に回復した。

cloud grass

Cloud grass refers to ornamental and native grasses in the genus Agrostis (family Poaceae), particularly Agrostis nebulosa, a delicate annual grass native to the Iberian Peninsula and northwestern Africa that produces large, airy, cloud-like panicles of minute spikelets on extremely fine, hair-like branches. The panicle's ethereal, misty appearance in mass gives the plant its evocative common name. It grows in dry, sandy soils and disturbed ground, completing its life cycle quickly in spring before summer drought conditions. Agrostis nebulosa is widely cultivated as an ornamental grass for cut flower arrangements and dried flower compositions, where its delicate panicles add texture and movement to floral displays. The genus Agrostis, bent grasses, encompasses dozens of perennial and annual species distributed across cool temperate and alpine zones worldwide, including the fine-leaved bent grasses used in golf greens and lawns for their dense, low-growing turf. Many Agrostis species are characteristic of acidic, nutrient-poor soils in heathlands, moorlands, and montane grasslands across Europe and North America.
