Structural parameters of vegetation and quantification of aboveground biomass (AGB) are important in forest monitoring to understand the vital cycle of ecosystems. This activity is even more challenging in seasonally dry tropical forests such as the Caatinga biome. The feasibility of using the terrestrial laser scanner (TLS) to measure structural parameters of plants and estimate aboveground biomass was investigated as an alternative to traditional methods. The study was conducted in an area of caatinga vegetation in the municipality of Petrolina, PE, Brazil, where three experimental subareas were selected to obtain measurements, cutting, and weighing of plants with a soil surface level diameter greater than 2.5 cm, totaling 97 plants. Scans were performed with the light detection and ranging (LiDAR) technology using TLS to obtain a three-dimensional point cloud. The correlation coefficient (r2) for plant height measured in the field and obtained by TLS was 0.80. The measures of trunk diameter at soil surfacelevel and at heights of 40 and 130 cm showed r2of 0.79, 0.78, and 0.76, respectively. New exponential allometric equations were generated using input variables obtained in the field and point cloud TLS. These results demonstrate the feasibility and potential of using LiDAR-TLS in dry forests, such as caatinga vegetation. This emphasizes the need to deepen approaches, tools, and techniques using this technology throughout the year to detect variations due to senescence and, therefore, the carbon cycle MenosStructural parameters of vegetation and quantification of aboveground biomass (AGB) are important in forest monitoring to understand the vital cycle of ecosystems.

Since the degradation of ecosystems is associated with an important loss of soil biodiversity, there is an urgent need for soil quality evaluation in order to identify and develop more sustainable prac-tices. A General Indicator of Soil Quality (GISQ) has been proposed by Velasquez et al. (2007) which combines a set of subindicators. These subindicators may also be considered as indicators of the performance of different ecosystem services (ES) such as soil structure and nutrient cycling. This study aimed to evaluate the impact of different land-use systems on soil quality in a Natural Reserve of South Brazil. Variables associated with soil diversity, fertility, physical properties and aggregate morphology were measured for each system. The highest GISQ average value was calcu-lated for the Forest (0.80), while this system also had the highest values for macrofauna, chemical and physical subindicators. PCA analysis showed a significant separation (p<0.001) of the Soybean crop from the others systems based on the lowest subindicators values. The GISQ reflected the pro-vision of soil ES, showing that better soil quality produces more ES. The methodology used can be applied extensively and allows monitoring of land-use changes through time. It could therefore gui-de the implementation of soil restoration technologies. |
