Science and Innovation for Improved Forest Health in TNNP Kirby Tulk, Janet Feltham, Rod Cox CIF-NL AGM Novemebr 20, 2014 TNNP- Ecological Context • 400 km2- Nearly 80 % forested • Boreal forest dominated by spruce and fir. • Moose were introduced to NF and are now hyperabundant. • No predation • Abundant supply of preferred forage species. • Other introductions include snowshoe hare, red squirrels, and slugs. • Intense and efficient fire suppression since the 1960’s- >80% of the forest is age class 5 or greater Moose- Forest Conversion in TNNP TNNP (72 km2) •Over browsing on the boreal forest has created a significant forest health issue in TNNP. Impaired 76 % •Already 13km2 (8231 hockey rinks) have been completely transformed into open fields-not enough trees to regenerate the forest. Severely impaired/failed 19% Level of Regeneration in Disturbed Areas Suitable regeneration 5% Fire Suppression in TNNP-THE BAD • Increased age structure resulting in loss of habitat diversity, lack of future habitat for SAR • Encroachment of climax species -Kalmia, loss of species diversity – plant and animal • Hazardous fuel accumulation HOW BAD CAN IT BE?? Other impacts... Red crossbill Newfoundland marten Erioderma pedicellatum Brief History of Moose Management in TNNP • Developed a hyper-abundant wildlife species management plan to lethally control moose. • Based on sound research- 16 peer reviewed publications on the effects of moose • Moose Management Area established for TNNP. • Year 4 of a moose reduction program (90 licenses issued. Approx. 60 moose taken from 2011-14 Year Success Rate Moose vehicle accidents Moose populatio n 2011-12 50% 10 230 2012-13 55.5% 22 200 2013-14 41% 12 194 Adequate hunting pressure • • < 20% Browse bF and Hardwoods are self-sustaining Condition prior to hunting • • • >50% Browse bF non-existent in 40 yrs HRWDS disappear in 100yrs Focused Moose Reduction • • Focused moose reduction-little gain Majority of bF communities are distal to accessible areas Fire Management in TNNP
