Restoration Approach at Myers Creek

Site History  Restoration Approach  Environmental Assessment Photos  Instream Construction  Culvert Replacement

OHA has implemented additional mitigation measures on this site, to:

a) Remediate some of the impacts created by loss of beaver, decades of overgrazing, and removal of woody debris

b) Raise the water table to support increased seasonal hydration of the floodplain soil and to support riparian vegetation

c) Increase the ability of the stream to capture sediment, and aggrade the streambed in closer proximity to the former floodplain

d) Increase the capacity of the stream and associated wetlands to store water for drought protection

Adding Beaver Dam Analogues helps provide similar ecosystem services to those generated by beaver, and fosters conditions that may support the return of beaver in the future. OHA utilized natural wood materials to slow down and back up the water so that spring runoff will inundate more of the soil and create the conditions necessary for wetland plants and animals to flourish. By supporting the reestablishment of natural ecological processes, OHA aims to help shift this parcel back to the healthy wetland it once was. Currently the habitat is too degraded to support beaver on much of the site. By raising the water table, OHA will help improve conditions so that more vegetation will grow, and in time, beaver will have the materials necessary help restore the channel.

In September 2014, OHA installed beaver dam analogues in Myers Creek to help restore the stream and wetland. OHA also placed large wood with rootwads attached in Myers Creek to help make up for the low ratio of large woody debris.
