Restoration management plan for the UFV campus forest Sierra Schwab, Dr Sharon Gillies University of the Fraser Valley Management Plan Foundations The Solution The Situation Why should UFV restore their campus forest? 1. Improvements in human disturbance • The Coastal Western Hemlock zone only comprises .2% of the worlds global forests Desired outcome • A pathway that limits soil compaction • Increase education and awareness about ecosystem restoration • Restoration could improve UFV student’s health and well-being • There is evidence to suggest low ecosystem function within the campus forest Actions required Reference Site Target Site • Remove gravel from current trail pathways • Construct a boardwalk above the old trail • Incorporate education boards Goals Similarities ✓ Plant dominance ✓ Soil nutrient levels ✓ Shannon’s diversity index ✓ Plant richness • Restore a disturbed forest • Enhance ecosystem function • Incorporate educational and social aspects in the campus forest • Soil nutrient analysis • Soil composition • Percent canopy coverage • Plant identification Desired outcome Differences ✓ Soil ph ✓ Soil composition ✓ Plant evenness ✓ Plant composition Methodology • Belt transects 2. Improvements in natural management Figure 1. Relative dominance of sixteen plant species along three belt transects at the Target site. Richness and evenness differences between the Target and Reference sites are displayed in Table 1 using two sample t-tests, p<.05, and n=3. • 15-min. observational walk Species ID 3 - Sow thistle (Sonchus oleraceus) 6 - Cleavers (Gallium aparine) 9 - Robert’s geranium (Geranium robertiannum) 12 - Barn yard grass (Echinochloa) • Reduce the total weed coverage Actions required • Cutting/hand pulling to prevent soil disturbance Figure 2. Relative dominance of seventeen plant species along three belt transects at the Reference site. Study sites have uncorrelated plant identification numbers. Richness Evenness Shannon’s Index Reference Site (Mt. Thom) 9.6 1.5 0.42 Target Site (UFV) 7.6 0.6 0.31 P-value 0.28 0.03 0.29 Species ID 4 - Robert’s geranium (Geranium robertiannum) 7 - Lady fern (Athyrium filix-demina) 10 - Sword fern (Polystichum munitum) 16 - Vine maple (Acer circinatum) 3. Improvements in biotic/abiotic interactions Desired outcome Table 1 • Increase native species • Increase species evenness • Indirectly enhance water capacity, soil biota activity, soil infiltration rate Ecosystem function analysis (of the target site) Target site (Chilliwack UFV campus) Reference site (Mt. Thom) • Higher weed dominance • Lower bacterial/fungi activity • Lower ph • Slow infiltration rate • Less vegetation cover Leads to… • Lower soil biota • Alluvial influenced • Glacial influenced Actions required • Lower available water capacity • Non-native plant competition Maidenhair fern (native) Bard yard grass (invasive) Glossary • High human disturbance • Low human disturbance (military base in WW2) • Re-introduce species such as: sword fern, lady fern, red elderberry, and wild Pacific bleeding heart • Add habitat features such as: snags, coarse woody debris, and nurse logs Weed species: any species that has been recognized by the BC Conservation Data Centre of BC flora (local hiking trail) Available water capacity: the minimum amount of water soil can retain and make available for plant use Infiltration rate: the speed at which water moves through the soil Alluvial soils: deposited by surface water that is formed by flooding Why was Mt. Thom chosen as the reference site? American trailplant (native) • Similar conifer species & age to the UFV forest (82-92 years old) • Similar crown closure (60-70%) Columbia spotted frog Various weed species Nurse log Robert’s geranium (invasive) Yellow-spotted millipede Common nipplewort (invasive) Wild ginger (native) References 1.
