Compact brome

<em>Bromus madritensis</em>, compact brome or Madrid brome, is an annual grass in the family Poaceae with an expansive native distribution across the Mediterranean basin, extending into parts of Africa, the Middle East, and central Asia. It has also been widely introduced to North America, South America, Australia, and other regions, where it is often considered an invasive weed in disturbed grasslands and shrublands. The species grows typically to 15–50 centimetres in height, producing dense, compact panicles with characteristic bristle-tipped spikelets that aid seed dispersal by attachment to passing animals and clothing. It thrives in dry, disturbed habitats including roadsides, agricultural margins, coastal scrub, and degraded grasslands, demonstrating strong tolerance for poor soils and seasonal drought. Compact brome is a pioneer species that colonises bare ground rapidly and can outcompete native herbaceous vegetation in fragile ecosystems, particularly in California chaparral and Mediterranean-climate shrublands. It is Not Evaluated on the IUCN Red List, consistent with its abundance and broad distribution. The species completes its life cycle entirely within a single growing season, germinating in autumn or winter and setting seed by late spring. Biological traits including precise lifespan data are inherent to its annual habit, but additional morphological and population data remain variable across its wide geographic range.

ヨーロッパヨシキリ

ヨシキリ（Acrocephalus scirpaceus）はIUCNレッドリストで軽度懸念（LC）に分類されています。分布域全体にわたって広く生息し、個体数は安定しており、早急な保全上の懸念はありません。
