A description of the field experimenta device set in a planted forest of mid Spain to assess the effect of thinning and single group selection cuttings on recruitment, underplanting growth and development, C stocks and fluxes and changes in stand structure, soil C stocks and soil biodiversity
Article
The group selection cutting system provides a promising technique for transforming monospecific even-aged stands into uneven-aged, mixed stands. However, this system has scarcely been used to regenerate Mediterranean shade-intolerant species. In this study, we analyze the height increment patterns of Pinus pinaster seedlings emerging in naturally r...

Diversification of forests, both in terms of structure and species, has been identified as one of the main strategies for adapting forests to climate change. Among the different options available for managers to promote diversification , regeneration cuttings are a suitable option to meet these objectives in adult stands close to rotation ages. The...

Forest adaptation to global change has become one of the main objectives of forest management in recent years. Species and structural diversification by thinning is a well-known adaptation measure, often applied by managers in monospecific even-aged stands. However, regeneration fellings may be more efficient for enhancing naturalization and resili...

La diversificación específica y estructural de las extendidas repoblaciones forestales españolas del Plan General de Repoblación Forestal de España es una de las materias pendientes en la gestión forestal, cuyo desarrollo es más importante si cabe en el contexto actual de cambio global. Las cortas de regeneración sobre repoblaciones protectoras de...

El cambio global supone un nuevo reto para la gestión forestal, al tener que adaptarse los tratamientos de mejora y regeneración a las nuevas condiciones climáticas. Con el objetivo de valorar cómo están regenerando las masas naturales de Pinus sylvestris del Alto Iregua (La Rioja), se planteó el seguimiento de dos áreas, situadas en Villoslada y O...

La biodiversidad es un tema relevante que ha alcanzado carácter prioritario en los últimos años, y que está muy relacionada con la diversidad estructural. En general, se asume que las masas arboladas irregulares presentan una mayor diversidad estructural. Sin embargo, la mayoría de los estudios al respecto se basan en el análisis de pequeñas superf...
Article
Full-text available
The actual context of global change necessary leads to the application of adaptive silviculture techniques in forests. Nevertheless, the particular situation of several protective reforestations, in which an inadequate management jeopardizes its stability, makes them a priority nowadays. Although its ages are still far from rotation ages, regenerat...
Article
Full-text available
The achievement of sustainable forest management requires the incorporation of ongoing environmental changes into long-term planning. Moreover, in time of climatic change and changing company demands, importance of Scots pine (Pinus sylvestris L.) is still increasing at the expense of other tree species due to its low ecological requirements. The a...
Article
Full-text available
Timber and biodiversity are considered two antagonistic ecosystem services (ES), largely influenced by silviculture and site ecological conditions. In order to address the trade-offs between these two ES over time, we performed a retrospective study at compartment level in the Pinus sylvestris forests of the Spanish Central Mountain System. Archiva...

Aim of the study: To analyse the decline in aged holm oak coppice forests as regards above-ground and below-ground fractions and physiological features. Area of study: Centre of the Iberian Peninsula (Guadalajara province). Material and methods: 26 pairs of holm oak stools with different vigour but with similar site and structural characteristics...

La utilización de nuevas tecnologías y aplicaciones informáticas está revolucionando las técnicas de inventario forestal. El acceso libre a imágenes de alta resolución, datos LiDAR y aplicaciones como QGIS, un sistema de información geográfica (en adelante SIG) libre y de código abierto, están favoreciendo en gran medida el desarrollo de estas nove...

Se presenta una experiencia sobre una masa de pino carrasco de 10 años de edad y elevada densidad (más de 10.000 pies/ha) en estado de monte bravo a bajo latizal, originada tras un incendio ocurrido en una repoblación (monte “Casa Eulogio”; Rivas-Vaciamadrid, Madrid). Se seleccionaron 400 pies/ha de porvenir, apeándose todos los pies vecinos en un...

It is widely accepted that site preparation techniques such as scarification can improve seed-soil contact and reduce weed competition thus enhancing seedling establishment. Nevertheless the efficacy of the treatment relies on its persistence which is expected to depend strongly on site conditions (soil + climate) and treatment features (size + dep...
Article
Full-text available
An expert on local flora usually is the best option for plant species selection in most ecological restoration projects; although species selection often needs to be dealt with swiftly as well as on a limited budget, and obtaining the opinion of a local expert may not always be an economically viable alternative. In such cases, species distribution...

Por tanto, la presente publicación tiene como intención estimular la actividad de conservación de los bosques españoles por parte de las Administraciones competentes y reclamar un mayor esfuerzo para su estudio en el marco del cambio climático y global por parte de la comunidad científico-técnica.

El presente trabajo corresponde a la última etapa de las experiencias iniciadas por la U.D.Selvicultura de EUITF en 1996 con el apeo de 24 encinas de edades comprendidas entre los 70 y 250 años. Tras dos controles del rebrote en los años 96 y 98, se completa el proceso de inventario con una última ronda de mediciones en junio de 2004, año 8 tras el...

The private state 'Cabeza de Hierro' (Rascafría, Madrid, Spain) is a singular and interesting example of the state of art for Spanish forest management. The forest covers about 1900 ha at the Spanish Central Range, with Scots pine as main species, though mixed with Pyrenean oak on lower elevations. The private ownership has been harvesting pine tim...
