Birdsfoot trefoil is the commonest legume of unproductive grasslands in the British Isles. It is intolerant of high nitrogen levels and is easily lost when grasslands are improved. It is a long lived perennial and is suitable for meadows. It is pollinated by bees and is the larval food for moth species. Birdsfoot trefoil can be distinguished from the other birdsfoot trefoil, in having a smaller stature, lighter green foliage and a solid stem.
