[7] [9] [13] [14] Ammophila arenaria built foredunes (the dunes closest to the beach) that are typically about 14 feet (4.3 m) high, which is much higher than the dunes associated with the native dune grass species Leymus mollis. [15] In the 1930s, A. breviligulata was introduced to about 3,000 acres (1,200 ha) on the Clatsop Peninsula in Oregon.
The Cyperaceae (/ ˌ s aɪ p ə ˈ r eɪ s i. iː,-ˌ aɪ /) are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges.The family is large; botanists have described some 5,500 known species in about 90 genera [3] [4] – the largest being the "true sedges" (genus Carex), [5] [6] with over 2,000 species.
Poa pratensis, commonly known as Kentucky bluegrass (or blue grass), smooth meadow-grass, or common meadow-grass, is a perennial species of grass native to practically all of Europe, North Asia and the mountains of Algeria and Morocco.
