FOREST SOILS IN SOUTHWEST NOVA SCOTIA

From Dr. David Patriquin, biologist [CLICK HERE TO VIEW]

(Page 1)

:- Acid rain, shallow soils, slow breakdown, dropping calcium levels.

:- Nova Scotia - poorest soils over largest area.

:- Forest soils losing more nutrients than those being replaced


(Page 2)

:- Nova Scotia in worst shape

:- Clearcutting exacerbates effects of acid rain by increasing nutrient loss

:- Other species being affected


(Page 3)

:- Nova Scotia has the poorest soils for clearcut forestry in North America and Europe

:- Few old growth stands

:- We cannot clearcut our forests again and again without penalty


(Page 4)

:- What happened in cod fishery is being repeated in Nova Scotian forests

(Page iii)

:- Effects of forestry on ecological values


(Page vi)

:- soil productivity


(Page vii) [also page 64]

:- Lands and Forests and Crown licensees must conduct or commission scientific research into impact of forestry on sensitive soils


(Page ix)

:- Private industrial land owners should be accountable for soil productivity

:- Crucial importance of decision-making based on peer-reviews science

:- More active research on soil sensitivity in the western region

:- More active research on impact on and options for minimizing the impact of forestry on soils


(Page 4)

:- Wind regime and thin soils


(Page 6)

:- Unacceptable impacts of clearcutting on sensitive and otherwise compromised soils


(Page 12)

:- Ecological forestry “requires (1) conceptualizing forests as ecosystems and (2) being concerned about the effects of forestry on various ecological values such as water, soil, and habitat for an array of species.


(Page 15) [also page 63]

:- Clearcutting should not happen in areas characterized by sensitive or thin soils (where there is a higher risk of acidification or erosion)


(Page 22)

:- The department's ecosystem-based management system; pre‐treatment assessment process; soil type


(Page 24)

:- The pre‐treatment assessment and prescription process do not appear to employ the Forest Ecosystem Classification manual, even though all the information needed to do so (Vegetation Type, Soil Type, Ecoregion) is collected


(Page 26)

:- Those licensed to conduct forestry on Crown land should be required to achieve outcomes – in areas such as soil productivity, water quality and wetlands, timber supply and quality, aesthetic impacts, biological diversity, public accountability, economic aspects, social consideration, and forest health – such as required under the State of Maine’s Outcome‐Based Forestry Policy.


(Page 29-30)

:- Full‐tree harvesting ,when it is combined with clearcutting, as it typically is, generally makes the ecological damage caused by clearcutting sufficiently adverse as to make it unacceptable on private or Crown land. The main concerns are erosion and the removal of nutrients from the soil and the impact of this on soil fertility, “a major concern in Nova Scotia.”


(Page 31) [also page 64]

:- Immediate and sustained scientific scientific research on potential adverse impact of Crown land forestry on sensitive soils, particularly on Crown lands in the western region


(Page 49)

:- The changes proposed for department's system of ecosystem‐based management will include measures to apply appropriate precaution to the kind of harvesting allowed on sensitive soils when applied to the western Crown lands.
