A Biophysical and Land Use Atlas for Maui, Hawaii

Stelfox, J.B.

A biophysical atlas of physical features (soils, climate, topography), plant communities and land use sectors (croplands, residential, transportation, mining, industrial and tourism) was assembled in Alces Online and then used to prepare an online Atlas. This atlas is now available for the educational sector (primary, secondary, post-secondary) for the State of Hawaii. These materials were presented to local governments, land trusts, and the University of Hawaii.

A Comparison of Land Use Options for the Mbaracayu Biosphere Reserve - Final Report

Matt Carlson

Unplanned and unsustainable land use has transformed the Atlantic Forests of Paraguay, Brazil and Argentina. In 1991, responding to the rapid loss of Atlantic Forest, the Government of Paraguay created the Mbaracayu Forest Natural Reserve (MFNR) and established the Cuenca watershed as a mixed-used protected area. Given the land use pressures facing the region, the future existence of healthy ecosystems within the Cuenca relies on balancing land use with conservation. The Mbaracayu program, run by the Fundacion Moises Bertoni (FMB), seeks to integrate a vision of sustainable and social development in harmony with the conservation of the MFNR. In response to the recognized need for a management plan, the FMB collaborated with the Alberta Research Council on the project "Capacity Enhancement for Community- and Ecologically-based Management in the Bosque Mbaracayu Biosphere Reserve, Paraguay". As part of the project, the land use simulation tool ALCES was applied to evaluate land use scenarios in the Cuenca. Applying ALCES contributed to the development of a management plan by informing the identification of sustainable land use options. The report is intended to communicate the ALCES tool and analysis, solicit feedback, and inform training of FMB staff to apply ALCES in the Cuenca.

A Fork in the Road: Future Development in Ontario’s Far North

Carlson, M., and C. Chetkiewicz. 2013

Ontario's Far North contains some of the world's most intact subarctic terrestrial and aquatic ecosystems. It is a stronghold for a number of fish and wildlife species such as woodland caribou, wolverine, and lake sturgeon. The region is also the homeland of Ojibwe, Oji-Cree and Cree First Nations who have established longstanding traditional cultural values and a unique relationship with this land that they have used and occupied for thousands of years. The environment in the Far North provides important "services" to people such as climate regulation, food, cultural values, and clean and abundant water supplies. The Far North also includes a wealth of natural resources such as minerals, hydropower development potential, timber resources, and other resource development opportunities. In 2010, the Government of Ontario committed to working with First Nation communities to develop land-use plans that support conservation and development of the Far North. An important step in the planning process is assessing whether the cumulative effects of the full suite of potential future developments are compatible with the aspirations of First Nations and Ontario. To support decision-making in this unique region, we applied a simulation model (ALCES®) to explore changes in the composition of regional landscapes associated with potential future mining, hydroelectric development, and forestry activity as well as forest fires, and the implications for woodland caribou, wolverine, moose, and the intactness of watersheds. Our study focused on the James Bay Lowlands, which includes the large mineral reserves in the Ring of Fire, numerous kimberlite deposits, including the Victor Diamond mine, and major rivers with hydropower potential such as the Attawapiskat, Moose, and Albany. To encompass the full extent of the Pagwachuan Caribou Range, the study area extended south of the James Bay Lowland thereby also incorporating portions of five Sustainable Forest Licenses that are managed primarily for timber production. The simulated development scenario resulted in a three-fold increase in anthropogenic footprint over 50 years, primarily due to road and transmission corridor expansion to support industrial developments. The spatial pattern of the simulated footprint differentiated between the dispersed road network associated with forestry in the south and the more isolated, but intensive, mining and hydroelectric Executive Summary To support decisionmaking in this unique region, we applied a simulation model (ALCES) to explore changes in the composition of regional landscapes associated with potential future mining, hydroelectric development, and forestry activity as well as forest fires, and the implications for woodland caribou, wolverine, moose, and the intactness of watersheds. vi Canadian Boreal Initiative | Wildlife Conservation Society Canada developments in the north. The simulated forestry activity in the south had consequences for the Pagwachuan Caribou Range where the risk to herd survival approached the high category and range disturbance exceeded a threshold of 35% – a guideline in the national caribou recovery strategy. Simulated impacts to wolverine were also greatest in the south, where expansion of the road network caused habitat suitability to decline. Land use impacts to wildlife such as caribou and wolverine may be exacerbated by climate change. As an example, the moose population was simulated to increase twofold when climate change was incorporated, which would likely cause the region’s wolf population to grow with negative implications for caribou herd viability. Simulated mining and hydroelectric developments were sufficiently isolated at a regional scale to avoid large impacts to caribou and wolverine. A greater concern, however, may be the consequences of these developments to the integrity of aquatic ecosystems. The watershed impact score increased for a number of northern watersheds, demonstrating that risk to aquatic ecosystems is likely to increase in watersheds that contain important natural resource regions such as the Ring of Fire due to the presence of multiple mining and hydroelectric developments. The outcomes of this pilot project offers important considerations when addressing cumulative effects in northern Ontario, including: the benefit to wildlife of limiting land use to isolated regions within an otherwise intact landscape; the need to improve understanding of the cumulative effects to aquatic ecosystems of multiple large-scale developments (e.g., mines, dams) within northern watersheds; and the potential for climate change to increase the sensitivity of wildlife to industrial land use. We hope these findings will inform land-use planning at both the community and regional scale and motivate additional analyses that are needed to comprehensively assess cumulative effects in Ontario’s Far North.

Alberta Southern East Slopes Integrated Land Management Pilot Project (draft)

Brad Stelfox, Mark Anielski, Matt Carlson and Terry Antoniuk

The Southern East Slopes Integrated Land Management Pilot Project (SES Pilot) used a real landscape and real data from southwest Alberta to evaluate how selected ecological and economic ‘performance’ outcomes could be achieved through different land management scenarios and how such integrated evaluations might be of use for policy analysis, economic trade-off analysis, and land use decision making. Economic and ecological indicators were developed using an integrated Genuine Wealth Accounting system (i.e. integration of natural, financial, and social capital accounts) to account for the physical and qualitative conditions and the monetary value, where possible, of key ecological assets, including water, carbon, and land. These indicators were then used to simulate potential trade-offs among market and non-market resource values using the ALCES© model, including the influence of pre-defined land management objectives on these indicators.

ALCES-based Habitat Simulation Modeling for Greater Sage-Grouse in Southeastern Alberta

Chernoff, Greg; Stelfox, Brad; Greenaway, Guy

In support of the Sage Grouse Recovery Action Group’s efforts to identify and quantify the potentially adverse effects of anthropogenic land use on sage grouse habitat, Alberta Sustainable Resource Development (Fish and Wildlife) retained the Miistakis Institute at the University of Calgary and Brad Stelfox of Forem Technologies Ltd. to develop, populate, and parameterize a cumulative effects simulation model for a 7X7 township region in southeastern Alberta. This model was subsequently used to conduct landscape-scale simulation modeling over a 50-year time period. The goal of the modeling is to generate plausible future scenarios based on current knowledge of landscape, ecology, and human use which explore potential trajectories for sage grouse viability, and to identify the drivers of change in a virtual environment. The modeling presented in this report is based upon the ALCES® software (Forem Technologies Ltd.). ALCES® is a landscape simulator that enables resource managers, society, and the scientific community to explore and quantify dynamic landscapes subjected to single or multiple human land use practices and various natural disturbance regimes. The model was identified in the Alberta Greater Sage-grouse Recovery Plan (2005) as a decision support tool allowing the Recovery Action Group to determine priority areas for focusing recovery efforts. Land use information (inputs) for the model were derived from existing data collected for the Southern Alberta Landscapes (SAL - formerly Southern Alberta Sustainability Strategy (SASS)) Project’s ALCES®-based cumulative effects modeling, and modified into a format appropriate for sage grouse modeling. ASRD Fish and Wildlife convened a workshop to collect the data required for the wildlife module of the model (i.e., sage grouse data). The Alberta Conservation Association (ACA)-supported workshop brought together sage grouse experts from Canada and the United States. Currently there is no comprehensive model to support decisions with respect to land use in the sage- grouse range of the province. Creation of such a model will greatly assist with integrating decisions for activities such as oil and gas development with sage-grouse conservation activities. This modeling approach may represent a prototypical method for recovery planning. By incorporating wildlife data, land use parameters, and management goals into a participatory process, alternate land use and management scenarios can be explicitly compared with reference to their impact on a target species. Along with the generation of a realistic base-case scenario for current landscape composition and future planned land use, this research has examined the impacts of changing future land use trajectories related to the energy sector as an example of the type of sensitivity analysis that is possible in the ALCES® modeling environment, and of the capacity of this type of analysis to provide valuable information about the impact of different types of land use on sage grouse breeding occurrence and success.

An assessment of the cumulative effects of land use and management in SSN

B. Wilson, M. Carlson, M. Iverson, and J. Straker, S. Sharpe

EXECUTIVE SUMMARY The St’kemlupsemc Te Secwepemc Nation (SSN) requested that ALCES Landscape and Land Use Ltd. (ALCES) conduct a cumulative-effects assessment for the SSN traditional territory, including any effects contributed by the proposed Ajax mining project. Simply put, cumulative effects are the changes caused by our actions today in combination with other past, and reasonably foreseeable human and natural disturbance. Critical components of this assessment include: • assessment over the entire SSN traditional territory, as well as the Ajax Regional Study Area (RSA) where appropriate; and • referencing current and forecast future conditions against ranges of natural variation approximating pre-contact conditions. This report provides a summary of the undertakings, findings and any recommendations emerging from this work for consideration by the SSN Review Panel in its deliberations regarding the proposed KGHM Ajax project within the SSN Traditional Territory. Simulation models are tools that provide insight into the potential outcomes of different land use management strategies. Models will not explicitly tell us what the “best” management objective or implementation approach is – this is the role of decision makers. ALCES is an acronym that stands for A Landscape Cumulative Effects Simulator. ALCES Online (AO) is a web-based GIS and landscape simulator for assessing the cumulative effects of multiple overlapping land uses and external stressors such as climate change. Indicators are measures of values of interest that help us understand the consequences of human land use and natural disturbance The ALCES simulation model was used to simulate ecosystems and forest fires during pre-contact conditions, and to additionally simulate the current and future effects of key human land uses, including mining (metal and aggregate), forest harvest, road construction, rural and urban residential growth, and recreation. These simulations were assessed for the cumulative effects on a range of land-use and ecosystem indicators, including five key indicators selected by SSN representatives: 1. land dispossession and tenure; 2. grasslands quantity and quality; 3. mule deer; 4. fish; and 5. an index of animal protein sources. Results of this work demonstrate substantial effects for all of these indicators from the precontact period to current conditions. All grassland and wildlife indicators show estimated declines within the SSN Traditional Territory ranging from 13% to 100%. In addition, development of the proposed Ajax mine project is shown to further contribute to decline in ALCES Landscape & Landuse Ltd. www.alces.ca ii future indicator performance for the grasslands and protein indices. Performance for the key selected indicators is summarized below: • Land dispossession and tenure – roughly 316,000 ha, or 25%, of the SSN traditional territory has been dispossessed through granting/sale of private lands, designation of provincial parks or other protected areas, and through direct construction of human footprint. These dispossessed areas are generally concentrated around the city of Kamloops and the grasslands to the south, as well as along the Thompson River valleys. Addition of non-forestry tenure types (mineral leases, guide-outfitter areas, range tenures, and the Agricultural Land Reserve) brings the total dispossessed land to 110% of the traditional territory. This analysis demonstrates that even without inclusion of forestry tenures that have granted forest-harvest rights and the ability to impose associated land management activities on the landscape, almost the entirety of the SSN traditional territory is occupied by at least one tenure type that is restrictive of SSN use of this land base. • Grasslands quantity and quality – grasslands comprised approximately 15% of the SSN traditional territory in pre-contact times. An analysis of current conditions indicates the absolute loss due to human land uses of almost 26,000 ha within the traditional territory, or approximately 14% of the original grasslands. These metrics are further pronounced in an examination of the Ajax RSA. In pre-contact times there were approximately 63,000 ha of grasslands in the RSA, or about 1/3 of the grasslands in the SSN traditional territory. Roughly 8200 ha, or 13%, of these grasslands have been lost due to human development at present, and future development over the next 50 years is projected to remove another 3400 ha, or 6% of the remaining grasslands. One of the larger intact grasslands in the RSA is the 2200-ha area north of the proposed mine development, and south of the Aberdeen neighborhood in the city of Kamloops. Declines in grassland quality are also estimated to have occurred and to continue occurring, both at the scale of the SSN traditional territory and within the RSA for the proposed Ajax mine. These declines are due to the combined effects of fire suppression, cattle grazing, introduction of non-native and invasive species, and physical removal of grasslands due to construction of human footprints. Integration of quantity and quality as an aggregate metric suggests that there has been an approximate 67% decrease in the integrity of native grasslands in the SSN traditional territory from pre-contact times to the present, and a 72% decrease within the Ajax RSA. • Mule deer – the habitat-effectiveness index for mule deer is currently 21% below the estimated lowest pre-contact level. This index is predicted to recover over the 50-year forecast driven by changes in forest demographics, but will still remain well below the minimum pre-contact level for this species. Fish – fish habitat is estimated for species that occur within the mainstems of the Thompson Rivers, including interior Fraser coho, an at-risk population. Average fish habitat values across the study area have declined by 27.5% from reference values, but some areas are higher, with declines in excess of 50%. These estimates of decline are conservative, in that they are based solely on a narrow assessment of mainstem habitat values, and do not account for temperature and flow effects within the river, nor population effects due to other factors. In addition, due to its limitation to the mainstem Thompson rivers, our analysis was not able to assess effects on fish inhabiting the Pípsell (Jacko Lake) area and associated watercourses. • Index of animal protein sources - The index of primary pre-contact terrestrial animal protein sources has declined by approximately 49% in current conditions from the precontact period, due both to degradation of grouse and mule-deer habitat and due to extirpation of elk and caribou from the traditional territory. Combining the effects of habitat degradation, extirpation, and land dispossession indicates an even greater effect: a 62% decline in availability of these protein sources under current conditions in comparison to the pre-contact period, as the majority of the highest quality habitat for the traditional protein species is largely inaccessible due to the granting of private title and construction of human footprint. As with the grasslands analysis, these effects are further pronounced in the RSA for the proposed Ajax mine – in this area, the decline in accessible terrestrial animal protein sources is 74% in current conditions compared to the pre-contact period. Addition of the fish indicator to the terrestrial protein indicators shows a total precontact protein indicator decline of 36% from pre-contact to current conditions. When the effects of tenure and direct displacement are added, the estimated decline is 42%. These and supporting analyses conducted for this report show the already substantial cumulative effects of land-management decisions and use in the SSN traditional territory, with generally large changes estimated from the pre-contact period to the present. Although the proposed Ajax project is relatively small, it is an additional stressor on the territory’s ecosystems and the organisms that depend on them, and its development would cause further loss to key SSN indicators, particularly grasslands and related species.

Assessing the Potential Cumulative Impacts of Land Use and Climate Change on Freshwater Fish in Northern Ontario

Chetkiewicz, C-L B., M. Carlson, C.M. O’Connor, B. Edwards, F.M. Southee, and M. Sullivan

Chetkiewicz, C-L B., M. Carlson, C.M. O’Connor, B. Edwards, F.M. Southee, and M. Sullivan. 2017. Assessing the Potential Cumulative Impacts of Land Use and Climate Change on Freshwater Fish in Northern Ontario. Wildlife Conservation Society Canada Conservation Report No. 11. The study is the first to project the potential impacts of development on freshwater systems in a 440,000 km2 region of northern Ontario over the next 50 years. The study examined the impact of high- and low-growth development scenarios that incorporated forestry, mining, and hydroelectric development, as well as climate change and forest fire. The response of fish populations was assessed by applying expert-derived models that describe relationships between simulated stressors (e.g., roads, dams, forestry activities, temperature) and species-specific fish sustainability indices (FSI) for walleye, lake sturgeon, lake whitefish, and brook trout. All four species exhibited increased risk over the simulation period, although lake whitefish were more tolerant of simulated changes in land use and climate change. Overall, climate change was the most influential driver of risk to freshwater fish, followed by hydroelectric dams. Climate change consistently exacerbated the effects of land use and natural disturbance changes under both scenarios – FSI declined faster or further when land use was combined with climate change.
