Herbicide Alternatives Program (HAP) – Current Activity (2016 to 2018)
2
Priorities – 2016 Monitoring field trip – Chapleau Crown Game Preserve
Mapping of herbicide-free areas (trial) Application of enhanced forest resource inventory Peer review of efforts to date Communication Create/update website Outreach Work planning for
3
Priorities – 2017 Enlist support of retired Industry /MNRF Forester having practical silviculture field experience and science background Trial use of vegetation ground surveys to support decision making First Nation technical review of survey methodology Implement mechanical site preparation trial – varying ground pressure to control depth of furrows Work planning for
4
2018 Priorities Kick-off - Wahkohtowin-RYAM Partnership
Year 2 of Vegetation Surveys First Nation students engaged quantitative assessment of vegetation in planted areas to enhance decision-making Field Tour(s) review results from 2016, visit mixedwood sites, discuss status of alternative approaches Using larger seedlings – decision support tools Communications Plan and implement Add HAP content to Wahkohtowin website:
5
Tracking Herbicide Use – Game Preserve
6
New Practices Forest Management Planning Adaptations
MCFN and CCFN - Land use and occupancy inventory Identify sensitive values from the inventory and apply protection buffer or Area of Concern Natural Springs Medicinal Plants Collection Areas Gathering Areas Burial Sites Worked with the communities and MNRF – facilitated by Barb Duffin GIS Manager with the Mushkegowuk Council Fine filter approach to ensure protection of point values only
7
Promising Practices Planned use based on forest conditions
Romeo Malette and Martel Forests Why regen delay is good on the RMF and MF – variable ground conditions Talk about where we rely on natural vs. artificial regeneration In addition to the variation in forest types, we also have variable ground conditions Productive soils, bedrock outcrops, sandflats, swamp – do have some drier ericacious sites where we have best bets for HAP on treated areas, but other much productive areas
8
Modified Site Preparation
Mechanical site preparation can stimulate root sprouting Ensure minimal ground pressure Late summer/fall timing when vegetation growth is reduced
9
Larger tree seedlings
10
New Practices Large Seedlings
Regular stock height – cm “optimum” Large stock height – 20 cm “optimum” Well balanced seedling – shoot/root ratio Use slightly larger containers (Jiffy pods) Modify growing regime to meet specifications - Added a new seedling supplier for 2019 for large spruce and jack pine: 200,000 trees
11
New Practices Innovation in application technology (AgNav systems)
Improved digital imagery and inventories Promoting natural regeneration on appropriate sites Depending on the forest unit, there are some areas that we expect to regenerate naturally, Generally hardwood forest units and lowland conifers Expect natural regeneration via suckering or careful logging takes place protecting advance regeneration or seed bearing trees For upland conifer sites and mixedwood stands, there is still the potential for natural regeneration Productive upland sites may have abundant natural regeneration and are stratified out from otherwise artificial treatments Headbangers – the delay allows the practitioner to see what is coming up naturally, and can avoid treatments in areas with heavy competition of crop species (poplar) and thus avoid multiple tending treatments or even failures.
