Remote sensors, onboard orbital platforms, aircraft, or unmanned aerial vehicles (UAVs) have emerged as a promising technology to enhance our understanding of changes in ecosystem composition, structure, and function of forests, offering multi-scale monitoring of forest restoration. UAV systems can generate highresolution images that provide accurate information on forest ecosystems to aid decision-making in restoration projects. However, UAV technological advances have outpaced practical application; thus, we explored combining UAV-borne lidar and hyperspectral data to evaluate the diversity and structure of restoration plantings. We developed novel analytical approaches to assess twelve 13-year-old restoration plots experimentally established with 20, 60 or 120 native tree species in the Brazilian Atlantic Forest. We assessed (1) the congruence and complementarity of lidar and hyperspectral-derived variables, (2) their ability to distinguish tree richness levels and (3) their ability to predict aboveground biomass (AGB). We analyzed three structural attributes derived from lidar data?canopy height, leaf area index (LAI), and understory LAI?and eighteen variables derived from hyperspectral data?15 vegetation indices (VIs), two components of the minimum noise fraction (related to spectral composition) and the spectral angle (related to spectral variability). We found that VIs were positively correlated with LAI for low LAI values, but stabilized for LAI greater than 2 m2/m2 . LAI and structural VIs increased with increasing species richness, and hyperspectral variability was significantly related to species richness. While lidar-derived canopy height better predicted AGB than hyperspectral-derived VIs, it was the fusion of UAV-borne hyperspectral and lidar data that allowed effective co-monitoring of both forest structural attributes and tree diversity in restoration plantings. Furthermore, considering lidar and hyperspectral data together more broadly supported the expectations of biodiversity theory, showing that diversity enhanced biomass capture and canopy functional attributes in restoration. The use of UAV-borne remote sensors can play an essential role during the UN Decade of Ecosystem Restoration, which requires detailed forest monitoring on an unprecedented scale.

Conteúdo: |
Avaliou-se o indice de area foliar, o coeficiente de extincao luminosa e o acumulo de materia seca em tres cultivares de Cynodon spp. (Tifton 85, Florakirk e Coastcross) submetidas a quatro intensidades de pastejo (5, 10, 15 e 20 cm) por ovinos em regime de lotacao contínua. O delineamento experimental utilizado foi o de blocos completos casualizados, com quatro repeticoes, em parcelas subdivididas, tendo na parcela as cultivares, e na subparcela, as intensidades de pastejo. Os maiores valores de íindice de area foliar foram encontrados na cultivar Tifton 85. A extincao de luz dentro do dossel do pasto variou com a cultivar, mes do ano e intensidade de pastejo. Os valores mais elevados de coeficiente de extinção de luz (k) foram observados nos pastos mantidos mais altos, dentro de cultivares, na Florakirk. As taxas de acumulo de materia seca foram semelhantes em todas as cultivares avaliadas, independentemente dos regimes de desfolha adotados. |
