Ecological Restoration


ERO has completed ecological restoration projects throughout Colorado for several decades and has the technical expertise to design revegetation and restoration plans that result in the long-term success of highly functioning native plant communities. ERO has successfully designed and overseen revegetation projects in wetland and riparian areas, native prairie landscapes, and higher elevation ecoregions throughout Colorado. ERO routinely conducts topsoil testing and analysis, develops topsoil management plansdesigns native seed mixes to match soil type, and selects appropriate plant material for both soil and hydrologic conditions. Our ecologists oversee site grading to ensure proper hydrologic conditions and seed and plant installation, implementing site-specific weed management strategies and providing recommendations to meet the restoration goals of each project.

Areas of Expertise

Wetland Mitigation and Restoration 

ERO has extensive experience designing and creating functional and diverse wetlands in the Arid West, Great Plains, and Western Mountains and Valleys. ERO’s wetland specialists have designed and monitored the construction of thousands of acres of wetland mitigation projects, from stream restoration projects to large wetland mitigation banks.

Construction  Observation  Services 

Working with engineers, landscape architects, and construction contractors, ERO has successfully overseen construction activities including grading, seeding, and planting native vegetation. Our knowledge of the key components to wetland and riparian areas, including hydrology, soils, and native vegetation, allows us to produce sustainable, functional, and diverse wetland and riparian communities that can enhance these ecological systems. 

Revegetation and Restoration 

ERO's restoration plans carefully consider the habitat, human use, and management needs of a project area, resulting in functional restoration solutions. ERO uses our understanding of ecological principles, such as succession and plant and animal interactions, to design restoration, revegetation, and enhancement plans for native plant communities. Our extensive experience with installation and monitoring ensures that our plans and specifications are clear and constructible so that the design is successful and sustainable. 

Noxious Weed Management 

ERO has extensive knowledge of the noxious weeds in Colorado, Montana, and Wyoming, and effective methods for controlling these invasive species. Throughout the Intermountain West, ERO has surveyed for noxious weeds listed by each state’s noxious weed regulations. Based on the results of these surveys and knowledge of local environmental conditions, ERO has completed noxious weed management plans that successfully eradicate or control noxious weeds while preventing harmful impacts on nearby stream systems, native ecosystems, and agricultural lands. 

Mitigation Banks 

ERO has been actively involved in the expansion of wetland and stream mitigation banks in the Denver Metro area. ERO ecologists have worked with project partners to interpret groundwater regimes and calculate appropriate ground surface elevations to support the rehabilitation and creation of new wetland banks. ERO has designed planting palettes to create various wetland types based on expected hydrologic conditions and has conducted construction observations to lead the appropriate placement of wetland species into various hydrologic zones.  

Monitoring 

ERO has monitored hundreds of wetland, riparian, and upland restoration sites throughout Colorado. ERO routinely completes annual monitoring following U.S. Army Corps of Engineers (Corps) guidelines, including documenting vegetation cover and diversity, tree and shrub survival, and noxious weed presence. ERO also conducts in-depth monitoring of various restoration sites using transects, plots, point-intersect, and other methods to document species presence, species richness, cover, structural diversity, tree and shrub vigor, and other indicators of revegetation and restoration success. ERO provides detailed monitoring reports documenting site conditions, recommendations for remedial or adaptive management actions, and overall success.
