Palomino, J, O Muellerklein, and M Kelly. 2017. A review of the emergent ecosystem of collaborative geospatial tools for addressing environmental challenges. Computers, Environment and Urban Systems 65: 79-92
We develop a typology of the emerging landscape of collaborative geospatial tools (those that use large, multi-scale, multi-temporal, and multi-dimensional spatial data to help collaborators share data, code, and results). Our typology is based on 31 tools, and uses a novel modified K-means clustering algorithm. We identify three primary clusters of tools, driven by required infrastructure and user involvement.

We simulated sealevel rise across existing and potential marsh elevations in two tidal wetlands differing in salinity. Plants were grown individually and together at five tidal elevations and harvested to assess differences in biomass after one growing season. Increasing inundation reduced biomass of the species commonly found at higher marsh elevations, with little effect on the species found along channel margins.

Across California, tree density in forested regions increased by 30% between the two time periods, whereas forest biomass in the same regions declined, as indicated by a 19% reduction in basal area.
