pigargo-americano

A ave nacional dos Estados Unidos e símbolo do sucesso conservacionista americano, a águia-careca tem uma envergadura de até 2,4 metros e habita florestas e zonas húmidas próximas de águas abertas em toda a América do Norte. Quase extinta na década de 1960 devido ao envenenamento por DDT e à caça, recuperou de forma notável após as proibições de pesticidas e a Lei das Espécies em Perigo.

cockscomb sainfoin

Cockscomb sainfoin (Onobrychis crista-galli) is a low-growing annual or short-lived perennial legume in the family Fabaceae, closely related to Onobrychis caput-galli and similarly characteristic of calcareous, well-drained grasslands, rocky slopes, and disturbed ground in western Europe, including Belgium, France, the Netherlands, and the United Kingdom. The species name crista-galli — Latin for cock's crest — refers to the distinctive winged, crest-like shape of the seed pods, which function as a burr-like dispersal mechanism attaching to the fur of passing mammals or to clothing. The plant bears pinnate leaves and erect racemes of small pink to red pea flowers from late spring through midsummer. It favours dry, open habitats on limestone or chalk substrates and is often associated with ancient grassland communities, roadside verges, and quarry spoil. Like other western European calcareous grassland specialists, it has declined in abundance with the intensification of agriculture, widespread application of herbicides, and the loss of traditional low-intensity grazing and hay-cutting regimes that maintained the open, short-turf communities it requires. Despite these pressures, the species retains populations across much of its range. It is Not Evaluated on the IUCN Red List globally, though national conservation assessments in some countries classify it as scarce or declining. Restoration of calcareous grassland management practices is beneficial for this and many associated plant species.
