Forest Management
and
Silviculture
Funding Shortfalls
There was a time when Government and the forest industry saw
the value in effective silviculture programs.
Starting in the 1960’s Government assumed responsibility for
forest renewal that lead to advances in renewal techniques including effective
site preparation, planting/seeding and tending. Forest nurseries were
established and seedling technology improved dramatically over time. Funding
for these early programs was derived largely from general Government revenues,
part of which was contributed from Crown charges on wood harvested from the
forest.
By the 1980’s there was a shift in forest management responsibilities
from Government to the forest industry as a result of changes in license
tenure. Silviculture funding and planning remained with the Government.
In the mid-1990’s the entire responsibility for planning and
silviculture was shifted to the forest industry. The level of expenditures in
the silviculture program was tied to long term strategic objectives in the
forest management plan. Funding for that level of silviculture was tied to contributions
made by the industry to a provincially held renewal fund. Essentially, for each
cubic metre harvested a given amount was held back and set aside for use in the
silviculture programs.
Before these developments forest renewal was a hit or miss
(mostly miss) process where forests were harvested and left for natural
regeneration. The original forests harvested post WWII were primarily conifer that
was destined for the pulp and paper and sawmilling industries. These stands
were either pure spruce or jack pine or some combination of these two with occasional
poplar scattered in the stands. For various reasons this process of natural
regeneration allowed favoured pioneer hardwood species at the expense of
conifer. The result, as a result of the lack of investment in silviculture was
that the young forest was comprised mainly of mixed species with much higher
levels of poplar and relatively low stocking of the more desirable conifer
species.
By the 1980’s and 1990’s the improvements in silviculture
practices along with much higher levels of funding resulted in much better
young forests following harvest. These results were consistent with forest
management planning objectives to recreate forest conditions found prior to
extensive logging and forest conversion. Extensive areas of spruce and jack
pine were very similar to those original conditions and met the long term
objectives for wood supply and habitat management.
All of this came at considerable cost. When times were good
in the forest industry with high demand and prices the industry was able to
invest in these expensive treatments. In return for those investments and with
expectation of more productive stands in the future the industry was able to
increase current harvest levels.
The forest industry failed in the mid-2000’s and the fallout
has been a disaster for the state of the forest. Pulp and paper mills closed due
largely to lack of demand and increasing costs and were dismantled. Sawmills
closed due to lower prices for their products coupled with higher costs for
scarcer raw material. Government scrambled to maintain whatever scraps was left
of the industry. Silviculture suffered as less money was available to execute
the appropriate renewal programs. More and more area was left for natural
regeneration whether or not it was appropriate for conditions encountered.
Tending plantations became unheard of and quickly grass and herbaceous plants
overran the young seedlings and survival plummeted.
The outcome is inevitable. Independent Forest Audits confirm
that lack of investment means objectives described in management plans will not
be achieved. Wood supply once considered sustainable will no longer be so.
Changes in forest cover will mean changes in wildlife habitat. On and on.
The same foresters who at one time were committed to
producing high quality, productive stands of spruce and jack pine, similar
those found in the forest prior to logging, are now investing essentially
nothing in silviculture and are content with whatever grows back post-harvest.
The result will likely be degraded stands of mixed woods with an overabundance
of second and third growth, poor quality poplar in place of those highly
productive conifer forest plantations of the 1970’s through to the 1990’s.
The public is assured through legislation that forestry in
Ontario is managed by highly qualified and committed registered professional
foresters. It is hard to accept that claim in the face of these changes in
forest renewal. Clearly, economics determines the effectiveness of silviculture
programs, not what is best for the forest and clearly the lack of investment is
damaging to long term forest health. When foresters consistently certify
silviculture prescriptions that they know, or should know, will not be
successful in terms of achieving future forest conditions the public has a
right to demand to know why.
At the same time though the fault doesn’t necessarily lie
with the role foresters play in this process. Foresters have little choice but
to do what they are told. Government and industry demand maximum volumes of
wood in management plans and foresters design silviculture programs that are capable
of achieving those volumes with the budget they are given.
1.
This approach to linking income to silviculture is
wrong. If there aren’t sufficient funds to do the work required to properly
regenerate the forest then the forest is no longer sustainable. This should not
be allowed to happen.
2.
Rehabilitating formerly degraded forest lands should
be an objective in future forest management plans. This would require an
assessment of recently harvested areas to determine current and future forest
condition. The assessment would be followed by a plan to carry out necessary
silviculture.
3.
The practice of listing multiple options for
regeneration on silvicultural prescriptions should be avoided in preparation of
management plans. Foresters should not have the option of planning for one set
of outcomes while at the same time selecting lower cost options that will yield
different outcomes.
