SUMMARY A mixed approach was applied using aerial LiDAR information to estimate the stand density in a Pinus radiata plantation. The methods used individual tree detection (ITD) information to improve stand density estimates from the approach-based area (ABA) method. Method 1, which corresponds to the traditional ABA estimation in a linear mode, obtained a RMSE = 23.6 % and a AIC = 840.9, where the LiDAR metrics used were in the 95 % percentile and the ratio between first returns over 1.3 m (COV). Method 2, which corresponds to an Individual Tree Detection (ITD) algorithm configured with a search window of 3 meters and a height defined by the 50th percentile, resulted in a RMSE = 49%. The mixed method 3 used the number of trees detected in method 2 as an additional metric in the ABA method, generating RMSE = 20.9 % and a AIC = 822.1. Method 4 was defined as mixed with error, which incorporated the number of trees estimated using the ITD method as another predictor variable, generating a RMSE = 21.3 % and a AIC = 835.2. The method with the best performance was 3, reducing 2.7 percentage points with respect to the RMSE of method 1 (traditional ABA). The integration of the ABA and ITD methods improved estimations of stand density, and also achieved better representation of the spatial variability of the number of trees at complete stand level

The records, obtained in evergreen and alerce forests, as well as in eucalyptus plantations, show markedly nocturnal activity. These findings represent a significant increase in the number of locations where the presence of this species has been confirmed.

used to generate seasonal, annual and monthly time series. The plantations showed a markedly seasonal response, with lower values in winter and higher values in spring/summer. Pinus spp. showed mean annual NDVI values higher than Populus spp. and Salix spp., according to its perennial ( Pinus spp.) and semi-deciduous (Salicaceae) characteristics. New information and methodologies regarding the spectral responses of forestation in the region was obtained from large volumes of data available in the Cloud, which made it possible to understand in detail the phenological patterns of different types of forestation.

is achieved through regression techniques. The objective of this work was to adjust allometric equations for the estimation of normal diameter ( dn ), total height ( at ) and volume ( v ) using the stump diameter ( dt ) for Abies religiosa in different regions of Mexico. A total of 2,599 data points from 20 forest management units were used to analyze the variables and their respective predictions through eight allometric equations, which were evaluated with different statistical criteria. The adjusted coefficient of determination (R 2adj ) explained 91 % of the normal diameter, together with the root mean square error (RMSE) of less than 4.75 cm with respect to the allometric equation (3). Another of the best options to estimate the total height is the Schumacher exponential (4) and the allometric (6) with values of R 2adj of approximately 50 %, accompanied by RMSE less than 5.03 m. However, for the volume of the forest, Schumacher’s equation was considered pertinent since it has a RMSE ranging from 0.00001 to 0.0026 m 3 with R 2adj that explains more than 74 % of the variation of the data observed in each UMAFOR. These regressions may be useful for the restoration of trees after an unplanned or unexpected felling event, as the results are statistically reliable.
