Welcome to CrustNet!

CrustNet is a globally distributed sampling network for biological soil crust (biocrust) ecology. This project implements a standard set of surveys and experiments in diverse biocrust habitats. These surveys and experiments were selected and collaboratively designed by biocrust scientists.

CrustNet is Launching now

CrustNet is entering its launch phase! Though the main recruitment push has not been initiated, requests to run nodes for the project are now being accepted via this intake form. If you want to know what it takes to run a node and would like to get involved, please see our FAQ page. The biocrust research community can also expect emails about the project during the next several months as recruitment continues.

Goals

CrustNet's scientific goals are to investigate:

  1. Determinants of global scale functional biodiversity of biocrusts
  2. Determinants of the variability and shape of the relationship between biodiversity and ecosystem function across ecosystems
  3. Effects of biocrust functional biodiversity on ecosystem resistance and resilience to physical disturbance and climate change

The network will connect scientists around the world to install CrustNet nodes on the ground. The project takes a tiered approach with basic and low costs surveys making up the base of the project (Tier 1) and then additional add-on experiments with increasing levels of commitment and investment for Tiers 2 & 3. Collaborators who are familiar with the biocrust and plant species of each node are invaluable to the work. Support for species identification is also available through the network of biocrust scientists and crowd-sourcing tools like iNaturalist.

Description
Canadian scientists Katherine Stewart and Diane Haughland and their graduate students meet us in the field for a CrustNet installation at Grasslands National Park, Saskatchewan, Canada.

Through this work, the CrustNet team hopes to inspire scientific and social engagement with biocrust ecology, to answer scientific questions and stimulate many more, to produce usable tools for future biocrust work including a trait database, and to grow & strengthen the international biocrust network.
