Back Cover: Top: Marshes are often nitrogen limited even though sufficient nitrogen (N) and carbon (C) are critical to sustain plant productivity and support biogeochemical processes such as decomposition and denitrification in these systems. Noll et al. examined the development of wetland soils over five decades in a constructed salt marsh. Their findings help restoration ecologists identify target soil properties such as bulk density, C, N, and C:N, for gauging wetland restoration success and estimating the time frame necessary for recovery.

Restoring habitat in this region is a large undertaking that requires cooperation among diverse landholders. Through a case study, Pérez et al. present a multi-step and multi-year model for Environmental Education (EE) developed to engage stakeholders in ecological restoration. As a result of the EE process, residents worked cooperatively with government and industry to establish native species nurseries and revegetate degraded lands.

Hummingbirds have been a culturally relevant wildlife group in Mexico since pre-Columbian times but are absent from many cultural heritage sites due to ecological degradation. To help re-establish a connection between people and their cultural and natural heritage, Barajas-Arroyo et al. conducted biocultural species enhancement at an archaeological site. They report on vegetation parameters necessary to attract target hummingbird species, and document how this enhancement has impacted visitor experiences at the site.
