Spatial and Temporal Dynamics of the Vegetation Cover from the Bijagual Massif, Boyacá, Colombia, during the 1986–2021 Period Gil-Leguizamón, Pablo Andrés Pereña-Ortiz, Jaime Francisco Sánchez Mata, Daniel Salvo-Tierra, Ángel Enrique Mercado-Gómez, Jorge David Morales-Puentes, María Eugenia Vegetación - Dinámica - Colombia Landscape changes based on spectral responses allow showing plant cover changes through diversity, composition, and ecological connectivity. The spatial and temporal vegetation dynamics of the 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-wooded mainland (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, followed by 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 continued to decrease (25.2%), Mpc occupied 52.9%, Hof 21.7% and Bdl 0.1%. Of the three fractions of the connectivity probability index, only dPCintra and dPCflux contribute to ecological connectivity. Hof and Dgnm show patches with biota habitat quality and availability. Between 1986 and 2021, Dgnm lost 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 sustainable agroecological and ecotourism proposals are required due to the context of the ecosystems. 2025-01-17T10:00:11Z 2025-01-17T10:00:11Z 2025-01-17T10:00:11Z 2024-03-25 journal article Gil-Leguizamón, P.A.; Pereña-Ortiz, J.F.; Sánchez-Mata, D.; Salvo-Tierra, Á.E.; Mercado-Gómez, J.D.; Morales-Puentes, M.E.
