ABSTRACT Accurate information is needed about burn severity caused by fires to design strategies for ecosystem recovery. The Mediterranean zone of Chile holds a high level of plant endemism. In summer 2017, nearly half a million hectares were severely burnt by fire in this zone. In this paper, we assessed the performance of three spectral indices used in mapping burn severity (difference Normalized Burn Ratio [dNBR], Relative difference Normalized Burn Ratio [RdNBR], and Relativized Burn Ratio [RBR]) on fragmented populations of the endangered ruil tree Nothofagus alessandrii, an endemic species of central Chile. The indices were obtained from Sentinel 2 images and their results contrasted with field measurements of severity recorded using the Composite Burn Index (CBI). The indices estimated the severity categories with a high overall accuracy obtained from error matrices and reaching values of 77.3, 76.0 and 69.3% for RdNBR, RBR, and dNBR, respectively. The surface estimated for the categories without damage (ND), low (L), and medium (M) were greater for the RdNBR and RBR indices than for the dNBR, while an opposite tendency was observed for the high severity category (H). Our results properly described the spatial variability of burn severity. This information may be useful for creating and managing plans for the recovery of highly fragmented and threatened deciduous ecosystems such as those dominated by ruil. We suggest that strategies for recovery or restoration should be oriented to the high fire severity zones, where reproductive individuals were lost, and the successful seedling recruitment is expected to diminish.

ABSTRACT The restoration of riparian habitats aims to provide habitat for birds and other environmental benefits; yet the evaluation of long-term outcomes is rare. To address this knowledge gap, we used bird and vegetation data from Coyote Creek Field Station (CCFS), in the southern San Francisco Bay Area, to assess the progress of two riparian revegetation projects (1987 Revegetation, 1993 Revegetation) over nearly two decades. Restoration success was measured by changes in 1) vegetation structure and composition, and 2) avian abundance, diversity, and community composition. We compared the two revegetated areas to a remnant riparian reference site and a managed floodplain overflow channel in three time periods (1996–1998, 2004–2006, 2012–2014) using ANOVA, Tukey’s HSD tests, and beta diversity analysis of avian community composition. Over time, the restored areas became more similar to the remnant riparian reference site in four of seven indices. The avian community became more similar across the habitat areas over time, although differences remained. Migratory birds declined across all habitat areas, while resident and wintering birds declined in one revegetated habitat only. Overall we found that different types of data told different stories, indicating both convergence with the reference site and ongoing differences. Our findings highlight the need for multifaceted approaches to evaluating restoration success.
