Editing Vernal pool (section)

=== Restoration ===
Vernal pools are prime habitats to be targeted for restoration work due to their value as hotspots of biodiversity as well as recent history of extensive destruction and degradation. However, there have been varying rates of success attributed to various restoration efforts. Several hypotheses have attempted to explain this:
: Hypothesis 1: Constructed pools are too deep.
: Hypothesis 2: Edges of constructed pools narrower than natural ones.
: Hypothesis 3: Constructed pools have steeper slopes than natural ones.

Results: Research suggest that the last two details (Hypothesis 2 & 3) are crucial in determining the habitat value of man-made vernal pools. In general, most constructed pools were too steep and did not have wide enough edges.
