AB Landscape changes based on spectral responses allow showing plant cover changes throughdiversity, composition, and ecological connectivity. The spatial and temporal vegetation dynamics ofthe Bijagual Massif from 1986 to 2021 were analyzed as a measure of ecological integrity, conservation,and territory. The covers identified were high open forest (Hof), dense grassland of non-woodedmainland (Dgnm), a mosaic of pastures and crops (Mpc), lagoons (Lag), and bare and degraded lands(Bdl). The Bijagual Massif has 8574.1 ha. In 1986, Dgnm occupied 42.6% of the total area, followedby Mpc (32.8%) and Hof (24.5%); by 2000, Mpc and Hof increased (43.7 and 28.1%, respectively),while Dgnm decreased (28%); by 2021, Dgnm was restricted to the northeastern zone and continuedto decrease (25.2%), Mpc occupied 52.9%, Hof 21.7% and Bdl 0.1%. Of the three fractions of theconnectivity probability index, only dPCintra and dPCflux contribute to ecological connectivity. Hofand Dgnm show patches with biota habitat quality and availability. Between 1986 and 2021, Dgnmlost 1489 ha (41%) and Hof 239.5 ha (11%). Mpc replaced various covers (1722.2 ha; 38%) in 2021.Bijagual has a valuable biodiversity potential limited by Mpc. Territorial planning and sustainableagroecological and ecotourism proposals are required due to the context of the ecosystems.
