The area that was redesigned into an ecosystem actually failed to attract the endangered species of clapper rails in California because of the following two reasons –
a)	Failed attempt of restoration of Cord grass ( a tree which is a dominant tree in the nesting habitat of clapper rail) . Even if few such trees were there they could not grow to their full height and thus were incapable of providing adequate nesting cover
b)	Due to the lack of predatory insect, some herbivore insect in the ecosystem attacked the green grasses thereby making the nesting inadequate.

-3x + 3(2x - 6) = 6
-3x +6x - 18 = 6
3x - 18 = 6
3x = 6 + 18
3x = 24
x = 8
hope this helped, blessing! :)
