Of the total area of the region, 19% is suitable for agriculture, depends on rainfall, only 30 % have potential soil and water for irrigation and 78 % of the area has the ability to silvipastoral exploration. The Caatinga is one of the most important biomes in Brazil, with its importance in endemic plants of forage value. The present study aimed to observe the consumption of forage plants for native goats directly in Caatinga, being recorded species consumed, frequency of consumption, location to record coordinates, temperature at the time of consumption, altitude, and finally, most frequently consumed species into two distinct areas, 60 km distant from each other. The plants most commonly consumed in the region 01 -São José da Tapera were: Angicos (Colubrina anadenanthera (Vell.) Brenan), Catingueira (Caesalpinia pyramidalis Tui), Mororó (Cheilantha bauhinia), Dainty gra...

Some areas in particular feature a concentration of large and numerous trees of Taxus baccata, a species that has attracted the interest of many researchers given its medicinal importance. The objective of this study was to analyze the biological and structural features of these unique ecosystems based on three large tree-mapped field plots using new methods. We developed a species abundance distribution and three species–area relations, and analyzed the small-scale structural patterns of each of the 15 tree species that occur in the plots. Species-specific details are presented for each of the three field plots, including the tree densities and average tree sizes, as well as the associated structural indices “species mingling”, “dominance”, and “size differentiation”. This includes non-linear relationships between tree density and neighbo...

We provide essential clarification regarding the definition and purpose of long-term field studies, review some of the extensive literature and discuss different approaches to collecting field data. We also describe two newly established forest observational networks that serve to illustrate the scope and diversity of forest field studies. The first is a large-scale network of forest observational studies in prominent natural forest ecosystems in China. The second example demonstrates observational studies in mixed and uneven-aged pine-oak forests which are selectively managed by local communities in Mexico. We summarize the potential for analysing and modeling forest ecosystems within interdisciplinary projects and provide argumentation in favour of long-term institutional commitment to maintaining forest observational field studies.
