Land Management Research Program

The Land Management Research Program conducts research to improve the effectiveness of land management and inform restoration of priority ecosystems on millions of acres including public lands such as National Parks, refuges, and other critical landscapes that support the biodiversity of fish, wildlife, and plant species, as well as thriving economies.

Carbon isotope trends across a century of herbarium specimens suggest CO2 fertilization of C4 grasses.

Increasing atmospheric CO2 is changing the dynamics of tropical savanna vegetation. C3 trees and grasses are known to experience CO2 fertilization, whereas responses to CO2 by C4 grasses are more ambiguous.Here, we sample stable carbon isotope trends in herbarium collections of South African C4 and C3 grasses to reconstruct 13C discrimination.We found that C3 grasses showed no trends in 13C discri

Structural heterogeneity predicts ecological resistance and resilience to wildfire in arid shrublands

ContextDynamic feedbacks between physical structure and ecological function drive ecosystem productivity, resilience, and biodiversity maintenance. Detailed maps of canopy structure enable comprehensive evaluations of structure–function relationships. However, these relationships are scale-dependent, and identifying relevant spatial scales to link structure to function remains challenging.Objectiv

Propensity score matching mitigates risk of faulty inferences in observational studies of effectiveness of restoration trials

Determining effectiveness of restoration treatments is an important requirement of adaptive management, but it can be non-trivial where only portions of large and heterogeneous landscapes of concern can be treated and sampled. Bias and non-randomness in the spatial deployment of treatment and thus sampling is nearly unavoidable in the data available for large-scale management trials, and the bioph

Prioritizing restoration and conservation of Wyoming’s sagebrush ecosystems for wildlife and sagebrush connectivity

To support strategic ecosystem management across the imperiled sagebrush steppe in Wyoming, USA, we developed an extension of the Prioritizing Restoration of Sagebrush Ecosystems Tool (PReSET). Our expanded tool leverages emerging spatial data resources to provide a structured but customizable set of scenarios that can guide landscape-scale planning efforts by prioritizing conservation and...

Prioritizing restoration and conservation of sagebrush ecosystems in northwestern Colorado

We are working with Colorado Parks and Wildlife (CPW) to pilot an expansion of the Prioritizing Restoration of Sagebrush Ecosystems Tool (PReSET; Duchardt et al. 2021) across northwestern Colorado. We are in the initial phase of a two-phase project where we are leveraging existing data resources to provide customized scenarios that directly guide landscape-scale conservation delivery by CPW. This...
