Full textPresently, Landscape indices (LIs) are increasingly used to quantify various aspects of different landscapes. In using a more holistic approach to landscape management, forest management is also taking this direction. Indeed, by controlling the spatial structure of forest mosaics, this type of management takes different forest values into account. For land managers, LIs represent an objective means to compare a landscape at different times or under different management strategies. However, it is presently difficult to use LIs to determine when two landscapes are “significantly” different because the theoretical distributions of LIs have not been determined. Hence one can say if a given landscape has a greater/lesser “fragmentaion” (for example), but one cannot say whether the fragmentation is significantly more/less in one landscape or another. In this study, the distributions of ten LIs widely used with categorical maps were determined empirically. This involved examining three landscape sizes on six different landscapes (forest mosaics) that were identified as being different by three different forest companies. The distributions of LIs were developed and tested using the Kolmogorov-Smirnov statistic to determine 1) if the LIs detected spatial differences among the six landscapes and 2) if the results conformed to a gaussian distribution. The results show that eight of the ten LIs tested can detect spatial pattern differences between “real” landscapes. However, they must be used at a specific scale to provide useful results. The analysis confirms also that landscape comparison using the selected LIs must be performed at a constant scale. Among the eight LIs for which the optimal “scale-LI” conditions were determined, only three provided normal distributions. These conclusions show that LIs could be part of a simple and robust methodology to characterise spatially forest mosaics and highlight their potential for uses in forest resources management.

Full textThe European “Habitats” directive urges EU state members to evaluate the state of conservation of their habitats listed in the Annex I, which form in France the so-called “Natura 2000” network. In France, the “Office National des Forets” is in a leader position, being in charge of 20% of all Natura 2000 sites. However, there is a concern about the compatibility of forest management practices commonly performed by this institution and the protective rules edicted by EU. In particular the maintenance of a good state of conservation of forest habitats can be questioned. The purpose of the present thesis was first to define a good state of conservation for forests of the Paris Basin, then to see, through several examples, whether their state of conservation was impacted by forest management. Herbs and humus/soil dwelling mosses were used as indicators, according to the phytosociological approach, as well as humus forms, using Humus Index and depth of holorganic horizons. Sampling was done in different management units, describing the forest cycle (synchronic approach) in homogeneous site conditions. For the habitat “Acidophilic atlantic beech-oak forest” (DH 9120), we showed an example of conversion of coppices-with-standards to full-grown stands, with sessile oak as a target timber species, and an example of an acidophilic beech forest where sylviculture was made more dynamic. For the habitat “Beech forest of the Asperulo-Fagion type” (DH 9130), our study was performed in three forests belonging to the same phytosociological syntaxon but located in three different climatic regions. In this case, too, we measured the effects of a more dynamic sylviculture. As a general rule, species richness increases under the influence of new sylvicultural practices. However, such an increase was not shown by mosses as well as by higher plants typically living in woodland. One explanation is the surface state of forest soils, which is strongly affected by exploitation traffic, mainly through soil compaction. Soil compaction disfavours geophytes, which are the main component of typical forest vegetation. Another explanation lies in the more dynamic sylviculture. The decreasing standing crop imposes a change in climate conditions, with more light and less humidity. This disfavours typical forest species, which commonly live in a shady and moist environment. Another important result concerns changes in humus forms under the new sylviculture. The Humus Index indicates a more rapid humification and mineralisation of topsoil organic matter. We hypothesize that soil biological processes are activated by more light arriving at the ground surface. At last, we want to highlight the importance of the geograhical range over which our results can be considered valid. The example of neutrocline beech forests shows that the appropriate scale for extrapolating our results is that of the natural (climatic) region

Full textIn hyperspectral imaging, each pixel is associated with a spectrum derived from observed reflectance in d measurement points (i.e., wavelengths). We are often facing a situation where the sample size n is relatively low compared to the number d of variables. This phenomenon called "curse of dimensionality" is well known in multivariate statistics. The mored increases with respect to n, the more standard statistical methodologies performances are degraded. Reflectance spectra incorporate in their spectral dimension a continuum that gives them a functional nature. A hyperspectrum can be modelised by an univariate function of wavelength and his representation produces a curve. The use of functional methods allows to take into account functional aspects such as continuity, spectral bands order, and to overcome strong correlations coming from the discretization grid fineness. The main aim of this thesis is to assess the relevance of the functional approach in the field of hyperspectral remote sensing for statistical analysis. We focused on the nonparametric fonctional regression model, including supervised classification. Firstly, the functional approach has been compared with multivariate methods usually involved in remote sensing. The functional approach outperforms multivariate methods in critical situations where one has a small training sample size combined with relatively homogeneous classes (that is to say, hard to discriminate). Secondly, an alternative to the functional approach to overcome the curse of dimensionality has been proposed using parsimonious models. This latter allows, through the selection of few measurement points, to reduce problem dimensionality while increasing results interpretability. Finally, we were interested in the almost systematic situation where one has contaminated functional data. We proved that for a fixed sample size, the finer the discretization, the better the prediction. In other words, the larger dis compared to n, the more effective the functional statistical methodis

Full textIn the context of currents environmental changes, and deal with anthropogenic pressures, the preservation of tropical forest has become a major issue. In this context, Madagascar island has implemented a new forest policy since 1990, having garnered the creation of protected areas. Ranomafana National Park has been created in 1991 and classify as World heritage in 2007. The establishment of a landscape dynamics monitoring at the local level, using remote sensing, allow analysis of forest changes faces anthropogenic pressures, taking into account the specificities of the study area. This monitoring allows to observe past and crurrent pressures on forest and point landscape trajectories. In addition, the forest bioclimatic activity monitoring examines the impact of climatic conditions and land use change on vegetation dynamics. The trend is the global reduction of forest cover mainly of lowland forest. Forest degradation rate during these past 25 years is estimated at 0,62%/year. These variations are different depending on the distance to the Park. Furthermore, analysis of photosynthetic activity reveals a general decline in values over the study period, regardless of the plant community type studied.Keys-words : Madagascar, remote sensing, tropical forests, Land-use change

Full textOver the last few decades, many researchers have addressed the impacts of forest loss on forest bird abundance. However, most of these works were conducted during the breeding season. The aim of my research was to document the effects of deforestation on bird populations during winter. Using an experimental approach, I also wanted to assess the effect of behavioral mechanisms potentially affecting population dynamics and spatial distribution of forest birds. Field work was conducted during three winters in Kamouraska County. The structure of 24 landscapes (500-m radius) was described from a satellite image. These landscapes represented a broad gradient of deforestation (forest cover 8–88 %). In half of these landscapes, we provided an unlimited source of food. I evaluated the effects of landscape structure 1) on the spatial distribution of the forest bird community, 2) on the fattening strategies, and 3) the anti-predator behavior of the Black-capped Chickadee (Poecile atricapillus). Forest integrity (a composite of forest cover and edge density) was positively associated with chickadee abundance and species richness in landscapes that were supplemented. However, in control landscapes, chickadee abundance and species richness tended to decrease with an increase in forest integrity. This suggests that the more forested control landscapes facilitated winter emigration when conditions deteriorated. Conversely in highly deforested and fragmented control landscapes, birds became “gap-locked”. Landscape structure did not affect chickadees’ energetic condition. However, food-supplementation improved it and affected the pattern of daily fattening as well. In the more deforested control landscapes, chickadees showed more willingness and ventured farther into the open despite a likely increase in the risk of predation. However, where ad libitum food was available prior to the experiment, chickadees always remained close to the forest edge, regardless of the level of deforestation.
