Description

The vegetation survey was performed in 21 circular plots of 10-m radius (250 m2) distributed as follows: 2 plots located in the area undergoing revegetation since 2014, 2 plots on the area undergoing revegetation since 2010, 6 plots on the area undergoing revegetation since 2006, and 11 plots on the area undergoing revegetation since 2002. Trees with diameter at breast height in the range of 2.5 – 10 cm were measured within the plots. In total, 717 trees were selected for measurement of diameter at breast height, wood density, total height and species identification. The coordinates of the center of each plot were recorded using a portable GPS (Garmin eTrex 10, Germany). The angle and distance of each tree from the center of the plot were measured, and its coordinates estimated. Stem diameters of all trees within the plot were measured using a calliper. Tree height was measured using a Vertex IV (Haglöf, Sweden). Crown diameter was measured in north-south and east-west directions. For species identification, a preliminary analysis of the flora of the area was performed following the guidelines developed by Idárraga-Piedrahita et al. (2011), Cardona et al. (2010) and Cardona et al. (2011). For the identification of the trees, leaf samples were collected from all individuals. The samples were preserved in alcohol for transportation to the laboratory, and subsequently dried and visually matched with species of the herbarium of the National University of Colombia. Some species could only be classified by genus because their reproductive morphology could not be determined, which is specifically relevant for the identification of Vismia sp. (Hypericaceae), Casearia sp. (Salicaceae), Cordia sp. (Boraginaceae) and Licania sp. (Chrysobalanaceae). Due to the complexity of their morphological and reproductive characteristics, genera Inga sp. (Fabaceae), Citrus sp. (Rutaceae), Ficus sp. (Moraceae) and Piper sp. (Piperaceae) were not classified at the species level. Herbaceous aboveground biomass growing spontaneously within the area and that was located outside of areas with forest cover was harvested at ground level in 120 plots (4 m2 each) with 30 plots per area undergoing restoration since 2014, 2010, 2006 and 2002. The total fresh weight of the biomass was determined in the field, and a subsample of 500 g was oven-dried for 24 – 48 hours for determination of dry weight. Purpose: The forest cover was surveyed for aboveground biomass estimation and species identification in February 2017.

Expected crawler behaviour

Use a stable, truthful User-Agent with product/version and a working contact URL. Across all IP addresses and HTTP connections used by one crawler identity, allow no more than 5 requests in flight and wait at least 20 seconds between request starts. Crawl URLs listed in the catalog sitemap, including file pages and download URLs when they are published, use conditional requests, honor Retry-After, and apply exponential backoff after errors.

The welcome page may link to the interactive repository for human navigation. Automated clients must not treat that human link as a catalog crawl target.

Read the live machine-readable crawler policy before and during a crawl. Stop crawling when it reports CPU or memory utilization at or above 80% and 80% respectively.
