Abstract
Due to limited funding for ecological restoration little is known about
outcomes 5+ years after initial implementation. In California,
understanding long-term restoration outcomes in grasslands is critical
because restoration is expensive, but grasslands are important for fire
resiliency, carbon storage and disproportionately harbor more rare species
compared to other habitats. We selected 32 grasslands from Santa Barbara to
Humboldt that were 3-30 years post-restoration. In 2019 we surveyed
absolute plant cover at species-level using multiple 50-m transects (3-16)
scaled to site size (0.5-15ha) and resurveyed ⅔ of the sites in 2020. We
conducted document analysis for sites with available documents and
semi-structured interviews with one or more land manager from all sites. We
used 25% native cover and 6 native species after 5 years as a standard
performance metric to equivalently compare restoration outcomes across
projects.

We found that 82% projects were successful based on the standard
performance metric, and up to 94% were successful when comparing against
project-based goals determined via document analysis and semi-structured
interviews. We found that non-native, cover was correlated with project age
post-restoration and that non-native species was strongly negatively
associated with native plant cover. Projects with more funding were related
to higher species richness, but not necessarily higher species cover.
Interviews with land managers revealed that practitioners agreed the
largest barrier to targeted restoration outcomes is limited funding which
leads to shortcomings in non-native species management and long-term
monitoring. Most restoration practitioners indicated they use certain
species for restoration because those species may have greater chances to
germinate, survive or recruit.   Join us!
