Q

Restoration work should begin in the healthiest areas first because: (3)

A

Social reasons - initial success increases credibility and support
Financial reasons - initial success increases potential for future funding

Q

The importance of monitoring (5)

A

Baseline monitoring should be conducted before remedial restoration takes place

After remedial restoration, monitoring should occur at regular intervals and be used to identify

  • when to shift from phase 1 to phase 2
  • effectiveness of meeting objectives at each
  • need for additional or revised treatments

As-built plans
When technical details are critical to include, managers might choose to publish plans as information posters stamped and dated
26
How do we tell wetlands from other ecosystems? (3)
Hydroperiod Presence of hydrosol soils Presence of hydrophytes
27
Hydrophyte (3)
Plants adapted to hydric conditions Adapted to anoxic conditions Obligate wetland plants and absence of obligate upland plants that are not adapted to flood conditions
28
Hydroperiod
Seasonality of water depth above or below soil surface
29
Hydrosols (4)
Soils that indicate hydric conditions Developed in anoxic conditions Wet, dark Characterized by their chemical content, physical structure
30
Marsh (5)
``` Wetland characterized by emergent herbaceous vegetation (as opposed to peat moss/lichens) Also called slough Most common wetland in N. America Rich in nutrients Dominated by reeds, rushes, and sedges ```
31
Fen (5)
Peat-accumulation wetland that has some drainage from surrounding mineral soil (is rheotrophic) Recharged by groundwater Less acidic than bogs More nutrients than bogs Dominated by moss, sedges, grasses, and black spruce
32
Bog (6)
``` Peat-accumulation wetland that has no inflows or outflows from surrounding soil (ombotrophic) Recharged by rain water Dominated by mosses and back spruce Highly acidic Low nutrients High water table ```
33
Peatland
General description of bogs and fens
34
Muskeg
Large expanse of peatlands (bogs and fens)
35
Rheotrophic (2)
Fed by flowing water | Eg. Fen
36
Ombrotrophic (2)
Fed by rain water | Eg. Bog
37
Wet meadow
Grassland with waterlogged soil near the surface but without standing water for most of the year
38
Potholes and playas
Both are shallow ponds but potholes are eroded by glaciers and playas are eroded by wind
39
Ponds and shallow open water (3)
Usually >2m deep Dry in late summer Too deep for emergent vegetation to establish
40
Swamp (3)
Freshwater wetland having woody vegetation and standing water for most, if not all of the growing season Heavy presence of trees and shrubs Nutrient rich, lush coniferous or deciduous
41
Riparian wetlands (2)
Different from swamp because it’s dry in times of growing season Heavy presence of trees and shrubs
42
How do we distinguish between wetland types? (4)
Hydrology Water chemistry/quality Vegetation Landscape context and conditions
43
What main factors hinders wetland protection at the provisional and federal levels?
No net-loss policy is not legally binding, so there are no reprecussions for wetland stressors
44
Canadian Wetland Classification System (2)
Commonly used system in Canada since Canada doesn’t have a federal, provincial, or territorial legal definition of a wetland Hierarchical
45
Levels of Canadian Wetland Classification System (3)
Class - classified as a marsh, swamp, bog, fen, or shallow/open water Form - given a form based on its surface morphology, hydrology, landscape setting, water chemistry, and underlying mineral Type - based on its vegetation structure
46
Form (6)
Second level of Canadian Wetland Classification System ``` Based on a wetlands: Surface morphology Hydrology Landscape setting Water chemistry Underlying material ```
47
Wetland hydrology is...(2)
The single most important determinant of: The type of wetland that exists The functions of that wetland
48
How does the hydroperiod have an effect on wetland plants and animals? (3)
Adult hydrophytes are adapted to submersion but some might need drawdown for seed germination Cattail growth is inhibited by drawdown so the hydroperiod maintains order and limits invasion Altering hydrology has been linked to invasive American Bullfrogs as they need 2-4 years of water to metamorphose
49
Water flowing into wetlands is:
Usually the main source of sediments and nutrients, and also a major source of contaminants and salts
50
The net balance of inflow and outflow for a wetland alters: (3)
Residence time of water and thus the settling of nutrients, sediments, and contaminants Water depth and thus temperature, dissolved oxygen, and pH Changes in water depth then affects the growth of wetland organisms (eg. Cattails)
51
Effective wetland conservation must:
Protect/restore native wetland hydrology, not just the area within wetland boundaries
52
Wetland functions (8)
``` Vary by wetland type, but often include: Biodiversity protection Water storage (flood/erosion control) Groundwater recharge Retention of sediments/nutrients/contaminants Nutrient cycling Decomposition Climate control (carbon sink very important to climate change mitigation) ```
53
Evidence of wetland stressors other than major hydrology changes (eg. Draining wetland) are...
Very subtle so managers need to analyze changes to community composition or species of plants and animals present
54
How have wetland stressors changed over time in B.C.? (3)
In the past, the dominant threat was large-scale agricultural drainage and water diversion Now, threats are more diverse and include draining, development, shoreline protection, riparian harvesting, invasive species, recreation, and climate change Future stressors include climate change as some wetlands no longer fill with water
55
The three biggest threats to wetlands in B.C. are:
Climate change Invasive species Agricultural cultivation
56
Some numbers of wetland losses (3)
50% of wetlands gone globally 70% fine in the Fraser River delta 85% gone in the Okanagan
57
Main categories of wetland management (2)
Wetland restoration | Wetland creation/construction
58
Wetland restoration (2)
Involves a range of activities from prevention of damaging practices (eg. Logging or grazing) to restoring native processes (eg. Hydrology) and species (eg. replanting vegetation) Protection makes the most sense
59
Why does wetland protection make the most sense? (2)
Because costs of creating a wetland are very high Restored/created wetlands rarely function the same as natural wetlands
60
Wetland creation/construction
Involves construction of wetlands where they didn’t previously occur for specific functions (eg. Flood control) Must avoid potential impacts (eg. Contaminant concentrations) Take into account future changes (eg. Climate change and urban development)
61
Particular attention should be given to 4 key factors when doing wetland restoration work:
Identify how hydrology has been altered Know the seedbank Ensure water inputs are clean Obtain appropriate permits
62
Definition of wetland (4)
Distinct ecosystem with static or flowing water that can be fresh or marine (if depth does not exceed six meters) Not always wet Water table close to the surface Must hold water at some point, and area must be inundated for a number of days in the growing season
63
What does monitoring do? (4)
Informs site assessment Helps assess success in reaching objectives Helps assess relative success of different treatments Helps identify the need for maintenance
64
Where should the executive summary appear in a report?
Roman numeral pages | Generally after the table of contents
65
Outline of executive summary should include: (4)
Location/importance of restoration Site/restoration history Effects of restoration/short comings Goals of restoration plan
66
Types of plots used in figure creation (5)
``` Scatter plot Clustered columns Stacked columns Secondary y-axis All with error bars ```
67
Figure formatting should have: (7)
``` Bars close together No grid lines No “location” = self explanatory Threshold line if applicable Error bars Units Legend inside graph lines ```
68
Common budget expenses (in order) (5)
Personnel - salaries of workers Travel/accommodations - lodging/vehicles Supplies/equipment - food, gear etc. Contractual - lab analyses Administrative overhead - administrative/indirect costs. Fraction of grant money that must be allocated to an employers administrative costs (eg. Insurance, rent, utilities, administrative staff)
69
Ratio of matching contributions
Funders often require that their funding be matched by other sources at a minimum rate/ratio
70
Cost sharing
Having multiple funders for one project
71
Status of funding (2)
Funders often request that you identify whether complimentary funding sources have been secured or only requested Some funders only request secured funding
72
Descriptions in budget
Budget items typically need descriptions. In many cases these are presented as rates
73
Budget justification
Sometimes descriptions are needed that are more detailed, and are generally presented as footnotes underneath the budget table
74
Hints for project budgeting (7)
Read funder requirements carefully Contact funder for clarification if needed Use costs that are suitable for high quality goods Avoid requesting an unreasonably high level of funding Avoid requesting an unreasonably low level of funding Re-allocating funds may be acceptable but double check with funder first Always return unused funds to funder after project is finished
75
Types of wetlands discussed (10)
``` Marsh Fen Bog Peatland Muskeg Wet meadow Potholes and playas Ponds and shallow open water Swamp Riparian wetlands ```
76
Sections of project budget (6)
``` Common expenses Ratio of matching contributions Cost sharing Status of funding Descriptions Budget justification ```
77
Why is understanding the breeding and migration phenology of local populations important to restoration efforts? (2)
Knowing the breeding time will indicate when managers should implement contraceptive measures for deer Knowing the migration time of Canada geese can tell managers when to put up or take down exclosures to reduce herbivory on sensitive ecosystems
