  1. EI Monitoring – Science Challenges

  2. Condition Monitoring Monitoring conducted over the whole park in the long term to detect major trends in park EI - “What is the state of park EI?” Management Effectiveness Monitoring Monitoring conducted over small areas to assess the effectiveness of specific park management actions – “What are we doing to improve park EI?”

  3. Common Issues/Common Solutions Given the same missing program elements we can work together to develop common solutions to park EI monitoring and reporting issues • Generally the same elements are missing in almost all park monitoring programs • Permanent, long term monitoring of ecosystem process measures at local and landscape scales • conceptual ecosystem models linking EI components (biodiversity, processes, stressors) for major park ecosystems to EI Measures and Indicators • ‘final suite’ of EI measures • management targets and thresholds for EI Measures • assessment methodologies for EI Indicators

  4. Science Challenges • How do we ‘capture EI’? • What do we measure? • What do our measurements mean? • Communicate!!!

  5. ‘Capturing EI’ • EI monitoring framework • major park ecosystems as EI indicators • core conceptual ecosystem models • local and landscape scales of measurement

  14. Roles of Ecosystem Conceptual Models • reduce ecosystem complexity:essential components of biodiversity, processes and stressors (EI) to prioritize monitoring measures; organize protocols and measures • COMMUNICATE approach and results: • science peers inside and outside parks • park managers, interpreters etc • all Canadians • improve EI assessments:conceptually related and co-located measures (long term plot data) provides internal logic • incorporate other park management activities:ecological frame for including restoration, infrastructure changes, visitor changes, operational changes, etc

  15. Forest EI Indicator Concerned Critical Healthy Stand Level Forest EI Landscape Level Forest EI Models tree productivity, songbird index, salamander populations change, foliar nutrient index, decomposition efficiency FF BioD Index (SAR, top predators, ungulates), CFBioD Index (ecosystem representation), connectivity, productivity Measures dbh, canopy condition, species composition, chopstick dry weight loss, songbird/salamander density, relative soil arthropod abundance, foliar nutrient concentrations SAR and other species population assessments, relative ecosystem abundance, Fragstats, AVHRR Data

  18. What to Measure and How to Measure it? • given the vast number of things we could measure, what do we measure? • PSOCLCIEIMs – the Holy Grail • measuring the park – study designs

  19. The Holy Grail • To find a parsimonious suite of co-located, ecologically inter-related EI measures that provide a comprehensive summary of park forest EI at an acceptable financial and human resources cost

  20. Forest EI Indicator Concerned Critical Healthy Stand Level Forest EI Landscape Level Forest EI Models tree productivity, songbird index, salamander populations change, foliar nutrient index, decomposition efficiency FF BioD Index (SAR, top predators, ungulates), CFBioD Index (ecosystem representation), connectivity, productivity Measures dbh, canopy condition, species composition, chopstick dry weight loss, songbird/salamander density, relative soil arthropod abundance, foliar nutrient concentrations SAR and other species population assessments, relative ecosystem abundance, Fragstats, AVHRR Data

  21. Selecting Measures • cost-effective, information-rich, low signal to noise • credible – supported by science community/research • feasible to measure (technical field staff); ‘same day suites’ • comes with a ‘story’, e.g., soil arthropods? • works well as part of a ecologically-integrated suite that covers conceptual model components • shared by monitoring partners (provinces/territories, communities, model forests, industry)

Core Bioregional Forest Landscape Model focal ungulate populations (moose, deer. caribou, hare) focal predator populations (bear, wolf, coyote, fox) size, vigour and genetic diversity of focal herbivore populations size, vigour and genetic diversity of focal carnivore populations predation habitat effects human effects herbivory spatial character, composition and productivity of forest communities change analysis (fragmentation, focal species habitat suitability, ecosystem representation), productivity, phenology, alien species landform processes acid deposition climate change distribution and character of park landforms (floodplains, moraines, karst, organics, avalanche tracks, glaciers, glacial outwash) glacier changes, flooding regimes, ice processes, avalanche rates disturbance

  26. Establishing Long Term MonitoringGeneral Rules • For all EI indicators data on biodiversity, processes and stressors should be collected at 2 scales – local and landscape • Representative local ecosystems of the major park ecosystem (forest stands, eelgrass beds, stream reaches, kelp beds, wetland types) need to be selected for measurement based on available resources, park management priorities and bioregional approaches • Whole park and greater park measures and assessments of indicators based on EO/RS – GIS data

  27. Changes in Forest Site - Spatial Variability

  28. Changes in Forest Structure – Temporal Variability

  29. FOREST ECOSYSTEM REPRESENTATION

  30. Selecting ‘Representative Ecosystems’ • average (mesic) ecosystems • most abundant ecosystems • ecosystems with high conservation importance • ecosystems most sensitive to known stressors • base poor ecosystems susceptible to acid rain • droughty ecosystems where prolonged summer drought is forecast

  34. Targets and Thresholds • What’s the question? • What’s the answer? • Developing targets and thresholds.

  35. The question is…………. “What is the state of park EI?”

  38. Establishing Targets and Thresholds Soil Decomposition Site 1 Landform: beach sands Soil: O.DYB moderately coarse, rapidly drained Veg Comm: Red Oak / Trembling Aspen Stand Origin: fire Site 5 Landform: glacio-marine Soil – O.GL; very fine, poorly drained Veg Comm: White Cedar / Balsam Fir Stand Origin: natural

  39. Clear Monitoring Questions • H01: local scale (stand level) forest ecological integrity has not changed significantly over the last 5 years in mature eastern hemlock ecosystems in Kejimkujik NP • H01.1: soil humus decomposition has not changed more • than 35% • H01.2: forest salamander population densities have not • decreased more than 12% • H01.3: foliar N concentrations have not decreased more • than 0.5% foliar dry weight • etc

  40. To monitor changes in nutrient cycling, we monitor soil decomposition using buried tongue depressors and measuring weight loss of the wood as an index of soil decomposition function Trees take up nutrients from the soil enhancing growth and delivering nutrients back to the ecosystem Tree needles, leaves, and branches fall to the forest floor Bacteria and fungi in the soil humus decompose the tree litter, making nutrients available for plant growth Communicating EI Monitoring Nutrient Cycling

  41. ‘Desired Condition’ forForest Landscapes: Rationale • most parks are not ‘natural’ and have had historical impacts that require management/restoration • active landscape management is required to meet park conservation needs – prescribed burning, ecosystem restoration, species re-introductions, alien invasives • management activities require performance reporting targets to assess progress towards desired goals; landscape targets will be set against patterns of natural successions and disturbance • ‘Desired condition’ targets for terrestrial landscapes need to be based on ‘desired conservation services’ the landscape can realistically provide

  42. ‘Desired Condition’ forForest Landscapes: Conservation Services • Habitat suitability: for focal species, e.g., charismatic, major park ungulates and carnivores, indicators, keystones, species at risk • Ecosystem representation: rare ecosystems, old forests, structural stage targets • Landscape productivity: within historical range of productivity as measured by NDVI or NPP • Landscape pattern: desired states for connectivity/fragmentation • Landscape processes: ice features (permafrost, thermokarst, solifluction etc), flooding regimes, mass wasting rates, • Operational and safety needs: fire/fuel management, RoWs, roads and visitor access/use, harvesting

  43. Time 1 Time 2 Desired Landscape Condition EI Assessment of Change Analysis Data

  44. Hypothesis Testing/Monitoring Questions • H01: landscape scale forest ecological integrity has not changed significantly over the last 5 years in Kejimkujik NP • H01.1: fragstat index target • H01.2: forest ecosystem representation target • H01.3: white tailed deer density is between 0.25 and 0.75 animals/ha • H01.4: cow:calf ratio in white tailed deer is greater than 1.2 • H01.5: NPP of forest landscapes is between ? and ? • etc

  45. EI Assessments • What is the state of park EI? • How to defensibly Integrate and assess monitoring results to report the state of the park? • IBI approaches – stress gradients • ‘Internal logic’ / rule systems based on conceptual ecosystem models
