“…Western and northern winds prevail in accordance with the latitudinal location of the depression and the deeply incised river valleys descending from the north, originating from slopes of the Tunkinskie Goltzy Range. The landscape-forming units of the Badary area are piedmont sub-taiga pine geomes (Mikheev & Ryashin, 1977;Atutova, 2018), which are characterised by a combination of gray forest soils and soddyslightly podzolic sandy loamy soils (Letunov, 1962). Gently sloping pine grass groups of facies with shrub undergrowth of Rhododendron dauricum L. represent the vegetation of the study area (Atutova, 2018).…”

Gently sloping pine grass groups of facies with shrub undergrowth of Rhododendron dauricum L. represent the vegetation of the study area (Atutova, 2018). However, there are no natural pine forests remained, which is caused by frequent wildfires that destroyed 80 km 2 of forest plantations per wildfire season (Lekhatinov & Lekhatinova, 2010).…”

A morphological variety of pyrogenic transformations characterises burnt areas of the Badary area of the Tunkinskiy National Park (Russia), from heavily damaged areas with a partially remained forest stand to bare spaces of tens of square metres. This enabled us to study the dynamics of the post-fire reproduction of Pinus sylvestris (hereinafter – pine) forests in areas with various environmental conditions. The main goal of our study was to determine the nature of the pyrogenic transformation of ecosystems and to evaluate the success of the forest reproduction. The studies were based on the geobotanical monitoring in two burnt-out areas, differing in the degree and area of wildfire damage due to a creeping fire in 2010. Between 2014 and 2020, we considered the multi-temporal specificity of the species composition of the forest stand, shrub layer, and plant communities. The emergence of the first shoots of undergrowth and new growth has been recorded. The projective cover and the dynamics of the species abundance in all forest layers were fixed. The analysis of the natural reforestation dynamics revealed a similarity of the main geobotanical indicators. Pine seedlings dominated in the undergrowth of the study sites, with a small proportion of Betula pendula. The shrub layer consisted of Rosa acicularis. Rhododendron dauricum has been found there only at the late stage of the study. In the herbaceous layer, the largest proportion was represented by meadow species, with a small participation of forest plants. Differences were revealed during the emergence of first seedlings of undergrowth and new growth, as well as in the size of projective cover of species in all forest layers. The first pine seedlings on a heavily burnt-out study plot were recorded a year earlier than on a less transformed plot. Nevertheless, the height increment and the projective cover of the undergrowth were significantly higher on the burnt-out area of a medium damage degree. On the heavily fire-damaged area, we observed pine seedlings planted by the staff of the Tunkinskiy National Park. A satisfactory rate of seedling survival at the initial stage and further deceleration of growth parameters have been noted. The obtained results indicate the reforestation success and, therefore, a favourable forecast of post-fire recovery of light-coniferous forests in the Badary area of the Tunkinskiy National Park.

“…A nivel internacional, las investigaciones asociadas con el estudio del paisaje han estado enfocadas en caracterizar la estructura (Alcántara y Muñoz, 2015;Erikstad, Uttakleiv y Halvorsen, 2015;Franch, Priego, Bollo, Cancer y Bautista, 2015;Kuzmenko, 2011;Lysanova, Semenov y Sorokovoi, 2011;Mar-dones, 2006;Ramón, Salinas y Remond, 2009;Suvorov y Kitov, 2013), diversidad (Fetisov, 2011) y transformación de los paisajes (Atutova, 2013). Además, de ser la base para evaluar la heterogeneidad (Suárez, Chacón y Ataroff, 2011) y el potencial ecológico de los geocomplejos (Kuznetsova et al, 2011), así como, para realizar el diagnóstico geoecológico de los mismos (García, Miravet, Salinas y Domínguez, 2019;La O, Salinas y Licea, 2012;Salinas, Mirandola, De Souza y Garcia, 2019).…”

Los paisajes físico-geográficos están conformados por geocomponentes de carácter natural; la interacción e interrelación entre cada uno de los elementos que los integran da origen a la expresión formal del espacio físico como un sistema definido por su estructura, funcionamiento y organización. El objetivo de este estudio fue clasificar los paisajes físico-geográficos que conforman a la Unidad de Gestión Ambiental (UGA) 33, a partir de la delimitación, tipificación y jerarquización de unidades territoriales basadas en el sistema taxonómico conformado por localidades, parajes complejos y parajes simples. Como resultados se obtuvieron 8 localidades, 10 parajes complejos y 21 parajes simples. Los paisajes que predominan en el área de estudio son las planicies tectónico-carsificadas onduladas formadas por calizas en clima cálido subhúmedo. La estructura espacial de los geocomponentes físico-geográficos que integran a la UGA permitió clasificar de forma integral y sintética al territorio, de forma que, el mapa de paisajes obtenido en este trabajo podría ser utilizado como un referente para el análisis de estudios posteriores.
