GAZP Database and Network

The two overarching goals of the GAZP are to compile existing data on restoration success for deeper analysis, and to link restoration researchers and practitioners through knowledge sharing.

Meta-analysis of Restoration Success

Primary Lines of Research

Compilation of existing data will focus on a few driving questions:

  1. What is the rate of arid and semi-arid restoration seed success globally?
  2. How is the rate of seed success changing through time? i.e. are we getting better at seeding?
  3. How do local and regional environmental conditions influence seed success?
  4. How do land use history and restoration strategies influence seed success?

As the project develops, these questions will expand with collaborative input from all participants.


Data requirements

Data is being collected primarily from scientific researchers and practitioners. Requirements for inclusion are as follows:

  • Collected in an ecosystem with less than 600 mm average annual rainfall.
  • Centered on restoration activities in a degraded site.
  • At least three species were seeded, at least one native. Seeding of multiple species in monocultures is acceptable.
  • Data includes seeding rate, able to be converted to seed per unit area of restoration.
  • Data includes above-ground plant density post-seeding OR
  • Data includes above-ground plant cover post-seeding.

Participation in GAZP requires the submittal of raw data of seeding treatments and outcomes as well as core meta-data on each seeding project. Participants are not limited in the number of projects they can submit. Because we understand everyone’s time is limited, data can be submitted “as is” in their raw excel form. Alternatively, a template can be provided for data formatting by each contributor. To be applicable, the contributed raw data should at a minimum have:

  • Seed rate data for each treatment in your work
  • Raw vegetation monitoring data post-seeding, either count or cover
  • Site details, which can be submitted either as a report or publication, or as information directly entered through the project’s meta-data spreadsheet.

The GAZP Network


The project was started in early 2018, and we are actively searching out arid and semi-arid restoration practitioners. Though data contribution is the primary method of collaboration at this stage, the role of individual contributors will grow and change as we move into data analysis and interpretation. Many restoration ecologists worldwide have joined the network and will receive regular project updates and opportunities to engage. To be added to our listserv, please go to the Connect page and fill in your contact details.

Additionally, this website will act as a growing foundation for sharing knowledge and connecting restoration ecologists regionally. Keep an eye out for new tools and interfaces coming in future!
