Title: New Advances in Markov Decision Process Models for Forest Management: Multi-criteria and Risk-sensitive Decision Making

Abstract: This work synthesis two recent studies extending the classic linear-programming formulations of Markov Decision Process (MDP) models to, nike air force 1 high donna respectively, handle multiple objectives and reflect risk preference, in forest decision making. nike internationalist mid uomo One study incorporated goal programming in MDPs with both average and discounted criteria to deal with multiple, Parajumpers often non commensurable and conflicting, Nike Air Force 1 homme objectives. The other adapted mean-variance or certainty equivalent optimization to MDPs with average rewards to reflect some consequences of the risk attitude of forestry decision makers. Both studies were applied to data for mixed softwood and hardwood forests in the southern United States, with multiple financial and ecological criteria. Jordan 2017 Femme The results show that given equal weights for normalized criteria, Adidas Zx Flux Homme Pas Cher minimum deviations from the highest diversity of tree size and species were achieved at the cost of, louboutin pas cher on average, Air Jordan 9 Homme one third of decline of other criteria from their maximum levels. adidas hamburg femme Compared with risk neutrality or risk seeking, financial risk aversion induced shorter cutting cycles and, New Balance 998 femme besides reducing expected annual financial returns and production, also lowered the expected diversity of tree species and size, stand basal area, stored CO2e,

Title: Resistance, resilience, or change: post-disturbance dynamics of boreal forests after insect outbreaks

Abstract: Understanding post-disturbance forest dynamics and promoting resistance and resilience to disturbances have emerged as prominent strategies to manage for changes in disturbance regimes. Despite progress made during the last decade, operational definitions of resistance and resilience have not been developed that can measure and then be applied to empirical data. In this study we develop a framework to jointly assess and quantify forest resistance and resilience based on changes in stand composition and structure during and following disturbances.  We apply our approach to boreal forests in Quebec affected by spruce budworm outbreaks to identify their main dynamics and to evaluate the intrinsic and extrinsic factors affecting their resistance and resilience. Quantitative metrics of resistance and resilience were used to compare forests with different pre-disturbance conditions and to evaluate the factors involved in their response. Assessing post-disturbance successional pathways allowed us to identify both stable and unstable states and potential pathways towards collapse. We observed that response to disturbance depended on pre-disturbance stand conditions. Black spruce forests are highly resistant to change caused by the spruce budworm, although this resistance is conditioned by outbreak severity that may change lower density black spruce forests to non-forested conditions (i.e. system collapse). In contrast, pure stands of balsam fir are not as resistant as black spruce, changing to different post-disturbance compositions after outbreaks, but are highly resilient (i.e. they return to the pre-disturbance state) when mixed with hardwood species.

Title: Usability Evaluation of the Forest Management Tool Prototype.

Abstract: The complexity of forest management software tools, induced by climate change and diversified forest demands, can lead to complex user interfaces, affecting thus the usability of the system(s).
ForeMA is a standalone modular application, aimed to support decisions related to forest management practices under climate change scenarios, able to assess the impact of forest stand management on multiple ecosystem services.
Our goal is to reduce the complexity in our interface design, while integrating efficient visualization techniques. In other words, develop a user-friendly tool and thus allow the users to minimize the learnability of the system and focus on its functionality.
The purpose of this presentation is to perform a usability evaluation by delivering a detailed demonstration of the system and asking potential end-users to provide feedback based on questionnaires and an open discussion.
We aim to use the output of this meeting to build a functional user-centric software, able to facilitate the workflow and meet the users’ expectations.

Title: Rocky pine forests in the High Coast Area (Sweden) and Wood Fungi and Forest Fire in a boreal context

Abstract: Almost all forests in Sweden are managed to some extent, only a small fraction can be considered natural. However, low productive forests, mostly without formal protection and privately owned, has rarely been managed and can have old-growth characteristics. Pine (Pinus sylvestris) forests in the High Coast Area (World Heritage Area) are extremely rocky and nutrient poor. We have investigated the structure, dynamics, human impact and fire history in this extreme environment. This was done by sampling and measuring size, age, fire scars, dead wood amount and quality at eight rocky pine stands. The structure is diverse (sizes and ages, Dead wood) but the density low. Frequent small fires have occurred and many of them (13) during the 1600s. The rocky pine forests in the High Coast Area are most likely undisturbed forests with low human impact, exhibiting several old-growth characteristics and can be a valuable habitat for organisms connected to sun-exposed DW. Wood fungi are the most important group of decomposers in boreal forests, and can be regarded as the “engineers of dead wood”. Forest fire has been the main disturbance in these forests and thus, boreal species has had to adapt to repeated fires. Industrialization drastically changed forestry and since the beginning of the 1900´s, forest fires have become very scarse, species dependent on repeated fires has consequently gone extinct or can be considered threatened or near threatened. The loss of wood fungi biodiversity can have a major impact on many other species due to their important role in dead wood dynamics. Our studies has been focusing on several aspects of wood fungi – forest fire interaction, including adaptation, community dynamics and combative interactions. Species that can be related to forest fire has adapted and is strongly favored by the disturbance. Our research can be used for restoration purposes, planning and performing restoration fires

Title: A demographically effective measure of population size for disturbance-prone ecosystems

 

Abstract

Stochastic disturbances, such as fire, are important in many ecosystems. Disturbances can drive population dynamics; stimulating large changes in population size and structure. Understanding how population structure at one point in time influences future population size is key to making realistic estimates of population changes in disturbance-prone ecosystems.  Yet how population structure interacts with disturbance regimes is rarely considered in conservation management.

A useful theory to account for the influence of population structure on future population size is the stochastic equivalent ratio. However, it is unclear whether this theory applies when stochasticity is large, such as in fire-prone environments.

Using a population model for a fire-killed obligate seeder from semi-arid Australia, I explore the utility of the stochastic equivalent ratio and ask, can the ratio: i) indicate the potential for future population growth? ii) identify appropriate fire regimes? and iii) estimate the abundance of seedlings that will emulate the trajectory of a reference population?

The method I evaluate, and then generalize, has wide applicability and great potential for achieving future plant and animal population goals when stochastic disturbances drive population dynamics.

Title: Wolf research in Scandinavia and population size estimation

Abstract: Wolves have recolonized the Scandinavian peninsula (Norway and Sweden) in the early 1980’s and since then have considerably expanded their distribution range and population size. In order to coordinate wolf research in Norway and Sweden and answer specific management and conservation questions, the SKANDULV (Scandinavian wolf project) has been created in the 2000’s. Research topics involve many different aspects: wolf ecology, predatory behavior, predator and prey interactions, interspecific interactions, etc. Additionally, ROVQUANT, a new project aiming at estimating population size of wolves but also wolverines and brown bears in Scandinavia has been initiated early 2017. This new project aims at estimating density of large carnivores using spatially explicit mark recapture models in Scandinavia.
