The success of native vegetation reclamation depends upon the knowledge about the species and planting strategies/models best suited for the area to be recovered. This work suggests more than 200 native species with their physiognomies of occurrence for the Cerrado biome, associated to its ecological strategy of occupation (covering or diversity) and main categories of potential economic utilization for using in eight planting strategies/models. It aims to guide technicians and owners of rural areas on the choice of species and appropriate strategies for woody (forest and savannah) vegetation recovery of Cerrado biome. Strategies for restoration with woody native vegetation vary from passive actions, as natural regeneration, to high intervention actions, such as those in Agroforestry Systems. Areas with greatest potential for natural regeneration have presence of regenerating seedlings, greater cover of native vegetation nearby and low presence of exotic and local competitors and it requires less labor and costs while areas with low potential for natural regeneration demand intense intervention and more expensive technics. All restoration action has risks and must be monitored and managed according to the expected results. These actions will indicate if your strategy was adequate and well conducted. Actions should start in small areas to support new decisions if something fails. To attend the law of Protection of Native Vegetation, these strategies can be applied in Brazil for Legal reserve (ARL) and Permanent Preservation (APP) areas.

The aim of this study was to evaluate the potential of luteal echotexture (mean pixel value and heterogeneity), as a tool for assessing luteal function during different phases of the estrous cycle in Toggenburg goats. Sonographic evaluations of the ovaries were performed daily in nulliparous goats (n = 21), using a 5MHz linear rectal probe, commencing at estrus (day 0). Blood samples were collected daily for plasma progesterone RIA and images recorded on VHS tape and then digitized in TIFF format at a resolution of 1500×1125 pixels. A representative elementary area (REA) of 5625 pixels (0.31cm2) of these images was analyzed using custom-developed software, for mean pixel value and heterogeneity. Mean plasma progesterone, luteal area and pixels all reached maximum values at approximately days 13 and 14, during luteogenesis. Luteolysis was characterized by an abrupt decrease in blood progesterone concentration following ovulation, and a gradual decline in luteal area and pixel values. The luteal tissue area was positively correlated with plasma progesterone concentration during both luteogenesis (r = 0.63; P < 0.05) and luteolysis (r = 0.50; P < 0.05). Weak correlations were recorded between the mean pixel value and luteal tissue area during luteogenesis (r = 0.34; P < 0.05) and luteolysis (r = 0.26; P < 0.05). Similarly, weak correlations between the mean pixel value and plasma progesterone concentration were recorded during luteogenesis (r = 0.24; P < 0.05) and luteolysis (r = 0.37; P < 0.05). The pixel heterogeneity was not correlated with luteal tissue area or the plasma progesterone concentration at any stage of the estrous cycle. The results show the association between the corpus luteum echotexture and steriodogenic function to be weak and the present ultrasound technology, to have limited potential in evaluating luteal function in goats.
