Recovery of great blue herons (Ardea herodias) within the Chesapeake Bay

The Journal of Wildlife Management, EarlyView.
We surveyed great blue herons throughout the tidal reach of the Chesapeake Bay in 2013 and mapped 423 colonies supporting 15,094 pairs. The population has increased more than four‐fold since the mid‐1970s. Colony size has declined. Invasion of colonies by bald eagles may be driving a change in spatial structure.

Quantifying Dynamics in Tropical Peat Swamp Forest Biomass with Multi- Temporal LiDAR Datasets [PDF]

, 2013
Tropical peat swamp forests in Indonesia store huge amounts of carbon and are responsible for enormous carbon emissions every year due to forest degradation and deforestation.

Northern bobwhites associated with native grass and shrubs have improved survival

The Journal of Wildlife Management, EarlyView.
Survival rates of adult northern bobwhites were improved by a combination of grazed native warm‐season grasses and well‐interspersed shrubs. Our study suggests that incorporating native warm‐season grass cattle forages into existing operations across the southeastern United States may be a viable working‐lands conservation strategy to create habitat ...

Use of GEDI Signal and Environmental Parameters to Improve Canopy Height Estimation over Tropical Forest Ecosystems in Mayotte Island

Canadian Journal of Remote Sensing
Canopy height is a fundamental parameter for describing forest ecosystems. GEDI is a spaceborne LiDAR system that was designed to measure vegetation’s vertical structure at a global scale.

Living on the edge: Habitat characteristics of northern myotis at the periphery of its distribution

The Journal of Wildlife Management, EarlyView.
Northern myotis selected tall trees with minimal decay, in patches with other roosting options. In our study area, these trees occurred in narrow bands within an agricultural matrix, differing from contiguous forest at the core of the species' distribution. Nevertheless, bats selected the tallest trees in the densest patches available.

Mechanisms of interference between kahikatea and grey willow in the Waikato [PDF]

, 2010
Research was undertaken to determine the nature of the coexistence between kahikatea and grey willow in the Waikato Ecological Region. Three main questions were investigated. Is grey willow inhibiting recruitment of kahikatea? If this is occurring, which
