The future of Silver fir under climate change and browsing

We are back on the million dollar question: how will our forests develop in this uncertain era of climate change? Yes, many study showed that changing climate might have strong impacts on the dynamics of temperate forests, but let’s not forget that management and other factors played (and will play) an important role for European forests. Among the different forest ecosystems in Europe, the mixed silver fir-beech Dinaric forests are one of the most fascinating to me. If you do not know much about them,Continue reading

The response of the forest to drought: the role of stand density and species diversity

Trees are beautiful complex adaptive organisms. As we see them standing immobile, deeply rooted to the ground and unable to move, we may think that they are defenceless to any change happening to their surrounding environment. In the case of drought, trees have evolved to use different strategies for facing water stress. However, intense and repeated droughts can induce changes in carbon allocation, regeneration rates and mortality. As the frequency and intensity of droughts are expected to increase in many regions due to climate change,Continue reading

Modeling fire size of wildfires

The extent of fires, their periodicity and their impact on terrestrial communities is always a concern. Wildfires play an important role in shaping landscapes and as a source of CO2 and particulate matter. Modeling the spatial variability of wildfire extent is an important subject in order to understand and to predict future trends on their effect in landscape changes.

Spraying forests does not get anything

Insect pests are a major threat to many forests worldwide, from boreal to tropical forest ecosystems. Some pests exhibit periodical outbreaks, after which their populations often crash as a result of natural biological control. In this study, authors assessed the performance of aerial spraying of insecticides on pine woodland stands to control pine processionary moth Thaumetopoea pityocampa (PPM) outbreaks in southern Spain.

Are forest disturbances amplifying or canceling out climate change-induced productivity changes in European forests?

Title of this post comes directly from recently published research paper. The international team of specialists has recently provided an overview of forest productivity changes in different forest regions in Europe under climate change, and tried to divide these changes into effects induced by climate change alone, and by climate change and forest disturbances.

Forest attrition distance reveals: deforestation was considerably higher in the western U.S.

The U.S. forests have been affected by dramatic land cover change over the past few centuries. In a paper published in PLoS One one month ago, Dr. Mountrakis and Sheng Yang, a graduate student, tried slicing deforestation a different way. Read more about a new way to measure deforestation, i.e. forest attrition distance, and and where in the U.S. it  was higher!

The Amazon rainforest lost its virginity millenia ago

Recently, drones have become very helpful in forest practices. This time, drones not only helped scientists to discover a new ‘Stonhenge’ in the Amazonian rainforest, but helped also to understand the forestry practices of prehistoric settlers in this area. Ecologists can be a bit shocked, as this discovery reverses assumptions that the rainforest ecosystem has been untouched by humans for millenia.

Protected areas in the world’s ecoregions: How well connected are they?

Protected areas (PAs) are the main instrument for biodiversity conservation, which has triggered the development of numerous indicators and assessments on their coverage, performance and efficiency. The connectivity of the PA networks at a global scale has however been much less explored; previous studies have either focused on particular regions of the world or have only considered some types of PAs.

How to evaluate state forest institutions?

Have you ever thought how to evaluate state forest institutions in your home countries? Researchers from Poland, Serbia and Germany have used a forest policy model to evaluate the activity of State Forests and Ministry of Environment in Poland. Read more what they have found, and think how such a study can be applied to state forest institutions in your home country.
