Resumen en inglés

Understanding traditional livestock management is essential in the design of more sustainable systems, given the forest loss associated to the growing demand for meat. In Latin America, where extensive livestock production is increasing, along with tropical dry forest (TDF) transformation, the role of small holders is critical for designing more sustainable management practices. This study is an integrated socioecological analysis of traditional livestock systems in a region with TDF in Mexico. The objectives were to: a) characterise the historical development and current state of livestock systems and silvopastoral practices, b) define the management strategies and their impacts on forests, and c) identify the regional and local socioecological drivers that influence decision- making processes in livestock and forest management. In-depth interviews were carried out to 32 cattle farmers and analysed using a qualitative-interpretative approach which included multivariate and narrative analyses. Three historical stages (colonization, promotion of livestock and forest conservation) had a strong impact in the development and current state of livestock systems. Access to natural and economic resources and proportion of plant cover (grassland/forest) were essential in defining four groups of management strategies.

The main regional drivers favouring or restricting production include climate, native vegetation, markets and public policies; at the local scale, socioecological factors, such as water availability, native vegetation, economic assets, local knowledge and their interactions determine heterogeneity in management strategies, decision-making processes and their impacts on forests. Adaptive management of livestock and forests in a context of limited economic resources has allowed the conservation of forest areas and the use of silvopastoral practices with local tree species. The integrated socio-ecological approach and the use of mixed methods allowed a better understanding of drivers and their interrelationships, the local knowledge, objectives and perceptions of farmers in the decision-making processes regarding livestock and forest management. Perspectives of farmers on resource use can contribute to the design of more effective and inclusive policies for sustainable livestock systems in the dry tropics.

Resumen en español

Actualmente los ambientes heterogéneos son los que predominan en los paisajes tropicales, por lo que estudiar la diversidad y la composiciónde especies en las comunidades avifaunísticas ha permitido entender la variación y la estructura de las mismas. Asimismo, esta información permite implementar estrategias de manejo y conservación en estos ambientes. En este estudio se evaluó la diversidad y composición espacial y temporal de la comunidad de aves en el Parque Nacional Lagunas de Montebello, Chiapas, en diferentes tipos de bosques y condiciones (bosques de pino, pino-encino, pino-encino-liquidambar, bosque mesófilo, vegetación riparia y zonas intervenidas). El muestreo se realizó de febrero a julio de 2017 en 110 puntos de conteo separados cada 300 m. En total se registraron 3,143 aves de 123 especies. La diversidad medida con el orden q=1 fue de 41.67 y con q=2 fue de 24.79 especies efectivas. La temporada de lluvias presentó una mayor diversidad de especies de aves que en secas. Los gremios mejor representados fueron los granívoros-frugívoros-insectívoros, los insectívoros y los omnívoros. Las zonas con intervención, así como los bosques de pino y la vegetación riparia presentaron la mayor diversidad de especies. En contraste, el bosque mesófilo de montaña, de pino-encino-liquidambar y de pino-encino presentaron especies raras y vulnerables como Setophaga chrysoparia, Pharomachrus mocinno y Penelopina nigra. Este estudio permite identificar sitios de monitoreo y de manejo forestal para el mejor ordenamiento en el parque nacional.

Resumen en inglés

Heterogeneous environments predominate in tropical landscapes, then studying diversity and composition of species in avian communities has allowed understand how it vary and is structured. This information also allows implementing management and conservation strategies in these environments. This study evaluated the diversity and spatial and temporal composition of the bird community in Lagunas de Montebello National Park, Chiapas, in different types of forests and conditions (pine forests, pine-oak, pine-oak-liquidambar, mountain cloud forest, riparian vegetation and modified areas). Sampling was carried out from February to July 2017 at 110 counting points every 300 m. In total, 3,143 birds of 123 species were recorded. The diversity measured with the order q= 1 was 41.67 and with q= 2 it was 24.79 effective species. Rainy season showed greater species diversity than dry season. The best represented guilds were granivores-frugivores-insectivores, insectivores and omnivores. The modified areas, as well as pine forest and riparian vegetation areas had the greatest diversity of species. In contrast, mountain cloud forest, pine-oak-liquidambar, and pine-oak forests had rare and vulnerable species such as Golden-cheeked Warbler, Resplendent Quetzal, and Highland Guan. This study allows to identify sites for monitoring and forest management that will allow for better planning in the national park.

Resumen en español

El mapeo de los impactos de la tala selectiva en la Península de Yucatán es importante para lograr la reducción de las emisiones de carbono y los objetivos de conservación de la biodiversidad. Objetivo. Evaluar la efectividad de la aplicación de técnicas de teledetección mediante el uso de imágenes LANDSAT 8 OLI para detectar la perturbación del bosque tropical a partir de la extracción de madera en cuatro bosques con manejo comunitario (ejidos). Además, evaluamos las diferencias entre ellos en términos de implementación de manejo forestal mejorado (IFM) y prácticas de aprovechamiento de impacto reducido (RIL). Metodología. Se calcularon los índices de vegetación y se realizó la clasificación de la cubierta forestal para hacer un mapa de las zonas taladas y no taladas y las perturbaciones específicas del aprovechamiento (por ejemplo, claros por la tala de árboles, carriles de arrastre, caminos forestales y áreas de acopio de madera) en las áreas de corta anual de 2014. Las evaluaciones de precisión se realizaron en función de los puntos de validación colectados en el campo después del aprovechamiento. Resultados. Encontramos que el 75% de las clasificaciones binarias (áreas impactadas y no impactadas) tenían precisiones globales medias superiores al 60%, lo que representa una precisión aceptable (40 a 70%), aunque el mapeo de las perturbaciones específicas de la cosecha tuvo poca precisión (<40%). Los índices de vegetación que obtuvieron los mejores resultados fueron el índice de vegetación de diferencia normalizada (NDVI), Tasseled Cap Greenness y Tasseled Cap Wetness. Los ejidos que aplicaron IFM y RIL impactaron un porcentaje menor de sus áreas de corta y menos área de bosque por metro cúbico de madera extraída, a pesar de intensidades de tala similares o mayores que los ejidos sin prácticas mejoradas.

Implicaciones. El monitoreo del impacto por la tala selectiva es importante para mejorar el manejo forestal y la certificación de sostenibilidad. Conclusiones. El mapeo y el monitoreo de los impactos de la tala selectiva por gestores y técnicos forestales se puede realizar de manera costo-efectiva utilizando imágenes LANDSAT 8, aunque la precisión se puede mejorar con imágenes de alta resolución.

Resumen en inglés

Background. Mapping selective logging impacts on the Yucatan Peninsula is important to pursuing carbon emissions reduction and biodiversity conservation goals. Objective. To evaluate the effectiveness of applying remote sensing techniques using LANDSAT 8 OLI imagery to detect tropical forest disturbance from timber harvesting in four communally managed forests (ejidos). We further assess differences among them in terms of implementing improved forest management (IFM) and reduced impact logging (RIL). Methodology. Vegetation indices were calculated, and forest cover classification was performed to map logged and unlogged forest and specific harvest disturbances (e.g. felling gaps, skid trails, logging roads and log landings) in annual cutting areas of 2014. Accuracy assessments were conducted based on validation points collected in the field after logging. Results. We found that 75% of the binary classifications (logged and unlogged forest) had mean overall accuracies greater than 60%, representing a fair (40 to 70%) accuracy, although mapping of specific harvesting disturbances had poor accuracy (<40%). Vegetation indices that performed the best were normalized vegetation index (NDVI), Tasseled Cap Greenness and Tasseled Cap Wetness. Ejidos that applied IFM and RIL impacted a smaller percentage of their cutting areas and less area of forest per cubic meter of timber extracted, despite similar or higher logging intensities than ejidos without improved practices. Implication. Monitoring selective logging disturbance is important to improved forest management and certification of sustainability. Conclusion. Mapping and monitoring impacts from selective logging by forest managers and technicians can be performed in a cost-efficient manner using LANDSAT 8 images, although accuracy could be improved with higher resolution imagery.

Resumen en español

Antecedentes y Objetivos: El fundo legal (FL) es una franja de vegetación forestal que delimita periféricamente a los poblados, provee de múltiples servicios ecosistémicos y forma parte de las reservas forestales comunitarias mayas de la Península de Yucatán. El objetivo de este estudio fue describir las formas de uso y manejo de la vegetación leñosa del FL por parte de los habitantes de la comunidad de Yaxcabá, Yucatán, México. Métodos: Dentro del FL se eligieron tres secciones a partir del número de caminos identificados. En cada sección se establecieron ocho parcelas de muestreo de 400 m² (20 × 20 m) y ocho parcelas más en vegetación madura (VM). En cada parcela se midió el diámetro de los tocones y se determinó su identidad taxonómica. Se estimó la riqueza, densidad y área basal de tocones y cada sección se contrastó con sitios con VM fuera del FL y con poca evidencia de aprovechamiento. Se aplicó una encuesta cerrada a la población para detallar las formas de uso local y manejo que los habitantes hacen en el FL. Resultados clave: Se registraron 58 especies útiles que comprenden 42 géneros y 22 familias de angiospermas, donde Fabaceae, Polygonaceae y Ebenaceae fueron las familias más abundantes. El aprovechamiento comprende una amplia variedad de especies y se cosechan pocos individuos pero el uso varía entre rumbos dentro de la comunidad; este aprovechamiento no afecta notablemente la composición de especies entre el FL y la VM. Conclusiones: Aun cuando existen secciones del FL en las que su cobertura vegetal se encuentra degradada, las estrategias de aprovechamiento actual permiten la permanencia y conservación de la composición de especies a nivel local. La intensidad de aprovechamientos en el FL se ve reflejada por una mayor cantidad de caminos y la distancia que hay entre ellos y los recursos forestales que utilizan. Palabras clave: conservación, manejo local, selva mediana subcaducifolia, vegetación secundaria.

Resumen en inglés

Background and Aims: The fundo legal (FL) is a strip of forest vegetation that peripherally delimits the villages, provides multiple ecosystem services and is part of the mayan community forest reserves of the Yucatan Peninsula. The objective of this study was to describe the forms of use and management of FL woody vegetation by the inhabitants of the community of Yaxcabá, Yucatan, Mexico. Methods: Within the FL, three sections were selected based on the number of roads identified. Eight sampling plots of 400 m² (20 × 20 m) and eight more plots of mature vegetation (MV) were established in each section. In each plot the diameter of the stumps was measured and their taxonomic identity was determined. The richness, diversity, density and basal area of the stumps and each section was contrasted with sampling plots with MV outside the FL and with little evidence of use. A closed survey was applied to the local people to detail the forms of local use and management that residents carry out in the FL. Key results: There were 58 useful species that included 42 genera and 22 families of angiosperms, of which Fabaceae, Polygonaceae and Ebenaceae were the most abundant families. Harvesting includes a wide variety of species and few individuals per species are harvested, but the use varies among courses within the community; this use does not significantly affect the composition of species between FL and MV. Conclusions: Even though there are sections of the FL in which its vegetal cover is degraded, the strategies of current use allow the permanence and conservation of the composition of species at the local level. The intensity of exploitation in the FL is reflected by a greater number of roads and the distance between them and the forest resources they use.

Resumen en español

Gran parte de las superficies forestales en México son manejadas por comunidades agrarias y ejidos, los cuales cuentan también con territorio destinado a la producción agrícola. Se realizó un estudio de caso en el ejido de San Andrés Hueyacatitla, municipio de San Salvador El Verde, estado de Puebla, donde las estrategias de reproducción de los grupos domésticos ejidales se centran en el manejo del bosque, las actividades agrícolas, así como el trabajo reproductivo y de cuidado. El objetivo fue conocer las afectaciones y estrategias de adaptación ante el cambio climático diferenciadas por género. Para la realización del estudio se tomó una muestra de 80 hombres y mujeres, integrantes de grupos domésticos con derechos ejidales. Se aplicó una encuesta y entrevistas semiestructuradas a informantes clave y se realizó observación participante. Se identificaron las afectaciones que los hombres y mujeres participantes en el estudio reconocen y experimentan de forma diferencial, las cuales son asociadas con la variabilidad del clima o cambio climático. Asimismo se detectó el desarrollo de estrategias de adaptación de acuerdo con sus asignaciones genéricas, conocimientos tradicionales y prácticas. Se encontró que los programas gubernamentales de conservación del bosque favorecen el desarrollo de estrategias de adaptación en los grupos domésticos ejidales para el manejo del bosque, lo cual sin embargo no disminuye plenamente la vulnerabilidad socioambiental en la zona de estudio.

Resumen en inglés

Much of the forest land in Mexico is managed by agrarian communities and ejidos, which also have land used for agricultural production. A case study was conducted in the San Andrés Hueyacatitla ejido, in the municipality of San Salvador El Verde, in the state of Puebla, where the reproduction strategies of ejido domestic groups focus on forest management and agricultural activities, as well as reproductive and care work. The aim was to determine the gender-differentiated effects and cli-mate change adaptation strategies. A sample of 80 men and women, belonging to domestic groups with ejido rights, was used for the study. A survey and semi-structured interviews were applied to key informants and participant observation was undertaken. The effects the men and women participating in the study recognize and experience differently, which are associated with climate variability or climate change, were identified. The development of adaptation strategies accor-ding to their assigned gender roles, traditional knowledge and practices was also detected. It was found that government forest conservation programs encourage the development of adaptation strategies in ejido domestic groups for forest management, which, however, does not fully reduce socio-environmental vulnerability in the study area.

Resumen en inglés

The Scientific Forestry and the associated management practices received significant attraction around the world which resulted in the birth of professional forestry education. In India, the professional forestry education was started in the year 1985 and currently offered at several State Agricultural and Central Universities. The Forestry and Agroforestry has also been incluzed as a subject in various under graduate and Post graduate program of State Agricultural and other conventional universities. This professional education in forestry and introduction of forestry courses to other degree programmes demand a comprehensive text book encompassing all the facets of forests. Against this backdrop, the current book on Introduction To Forestry & Agroforestry is conceived to cater to the needs of professionals in B. Sc (Forestry), B.Sc (Agriculture), B.Sc. (Horticulture) and B.Sc (Sericulture) courses offered at State Agricultural Universities and undergraduate programme of Botany and Environmental Science courses offered at Conventional Universities. Besides, the book can also act as a fast and ready made reference material for the graduates aspiring for State and Central Forest Service Examinations. For any beginner in professional forestry education and competitive examinations, this book will be an asset to understand and learn the principles and practices of forestry coupled with other recent developments in forestry sector.

Resumen en inglés

Changes in land cover have a direct impact on forest ecosystem goods and services. In this study, changes in land cover in Sierra de Juarez–Oaxaca ecosystems were estimated using a consistent processing of Landsat images and OBIA methodology. Additionally, landscape analyses using FRAGSTAT were conducted. In 2014, Sierra de Juarez–Oaxaca was covered by approximately 84% of forests, mainly pine-oak and cloud forests. After extensive deforestation until 2001, this trend was reversed and the forest cover surface area in 2014 was slightly higher than in 1979. The comparison of the landscape structure of the forested and agricultural lands suggests an increase in habitat heterogeneity. However, interspersion and juxtaposition indices, showing the patch shape by patch area and perimeter, were similar throughout the study period (1979–2014). Social and economic drivers can explain this situation: namely, community organization, forest enterprises, payment for ecosystem services programs, and changes of agricultural activity. Communities in the Sierra of Oaxaca have reforested degraded lands, created community forest enterprises, and preserved the forest under conservation schemes like those proposed by the Mexican payment for ecosystem services programs. However, their sustainable management faces internal challenges and has become highly dependent on political and institutional decisions beyond their control.
