Presentation Transcript

Slide 1

Rivulets and Communities PFC Assessment Approach & Definitions

Slide 2

What is conceivable? Bear Creek, OR 1977 1988

Slide 3

What is conceivable? Burro Creek, AZ 1981 2000

Slide 4

PFC Assessment Development ID Team from the BLM, the FWS, and the NRCS with skill in vegetation, hydrology, soils, and science. Four year think about period in the 12 Western States (1988-92). Gathered soil, hydrology, and vegetation data at field destinations – ESI Identified normal and imperative properties/forms that could be outwardly evaluated.

Slide 5

PFC Development proceeded with Incorporated these components into lotic & lentic agendas. Draft report TR 1737-9 & 11. Extra field test. Concluded TR 1737-9 (1993) & 11 (1994) Riparian Coordination Network Review User Guides TR 1737-15 (1998) & 16 (1999)

Slide 6

Riparian-Wetland Areas Vegetation Landform, Soil Water

Slide 7

The PFC Assessment Tool Requires an interdisciplinary (ID) group Vegetation Hydrology Soils Biology Local, on-the-ground involvement in translating quantitative examining procedures that bolster the PFC agenda

Slide 8

PFC Assessment Method Requires an interdisciplinary group with solid specialized abilities and experience. All individuals from the group can take part. Water Soil, Landform Vegetation Common Vocabulary

Slide 9

Lotic Lentic Standing water Running water

Slide 10

Wetland Area Inundated or immersed by surface or ground water Frequency and term adequate to bolster a commonness of vegetation ordinarily adjusted for life in soaked soil conditions Marshes, swamps, lowlands are illustrations Lentic = standing water frameworks

Slide 11

Riparian Area Transition between the wetlands and upland regions Vegetation and physical (soil) attributes mirror the impact of changeless surface or subsurface water Land along streams, shores of lakes are cases Lotic = running water frameworks

Slide 12

Perennial Stream A stream that streams persistently. Lasting streams are by and large connected with a water table in the areas through which they stream.

Slide 13

Intermittent Stream Meinzer's recommendation (1923): stream ceaselessly for times of no less than 30 days A stream that streams just at specific circumstances of the year when it gets water from springs or from some surface source, for example, softening snow in rocky zones.

Slide 14

Ephemeral Channel Meinzer's proposal (1923): don't stream consistently for times of no less than 30 days A stream that streams just in direct reaction to precipitation, and whose channel is at all circumstances over the water table.

Slide 15

Interrupted Stream A stream with discontinuities in space

Slide 16

Riparian Proper Functioning Condition Term is utilized as a part of two ways Assessment handle Defined on the ground condition How well the zone's physical procedures are working State of flexibility that will permit a territory to hold together amid respectably high streams, for example, 5-, 10-, and 20-year occasions

Slide 17

PFC Assessment is a Qualitative Tool

Slide 18

Dissipate stream vitality Reduce disintegration Filter residue Capture bedload Aid floodplain advancement Improve floodwater maintenance and groundwater revive Develop root masses that balance out stream banks Increased water quality and amount Diverse ponding and channel attributes Habitat for fish and untamed life Greater biodiversity Lotic PFC Adequate vegetation, landform or extensive woody material to: To Yield Physics Values

Slide 19

Dissipate energies – wind, wave, overland stream Reduce disintegration Filter silt Improve floodwater maintenance and groundwater energize Develop root masses that balance out islands and shoreline highlights against cutting activity Restrict water permeation Increased water quality and amount Diverse ponding and channel attributes Habitat for fish and natural life Greater biodiversity Lentic PFC Adequate vegetation, landform or trash is available to: To Yield Physics Values

Slide 20

satisfactory vegetation

Slide 21

sufficient vegetation

Slide 22

satisfactory landform

Slide 23

sufficient landform

Slide 24

sufficient expansive woody material

Slide 25

satisfactory huge woody material

Slide 26

Dissipate stream vitality Reduce disintegration Filter dregs Capture bedload Aid floodplain advancement Improve floodwater maintenance and groundwater revive Develop root masses that settle stream banks Increased water quality and amount Diverse ponding and channel attributes Habitat for fish and untamed life Greater biodiversity PFC On-The-Ground Condition Adequate vegetation, landform or vast woody material to: To Yield Physics Values

Slide 27

Potential The most elevated environmental status a riparian-wetland region can accomplish given no political, social, or efficient limitations, and is frequently alluded to as the potential common group (PNC).

Slide 28

Capability Highest biological status a territory can accomplish given political, social, or financial imperatives, which are frequently alluded to as constraining variables.

Slide 29

Functional - At Risk Riparian-Wetland Areas that are in Functional Condition But a current quality Soil Water Vegetation Makes them vulnerable to debasement amid high-stream occasions, for example, the 5-, 10-and 20-year occasions

Slide 30

Nonfunctioning Areas that are obviously not giving satisfactory vegetation, landform, or extensive woody material To: Dissipate stream vitality Improve floodwater maintenance & groundwater revive Stabilize streambanks And different qualities basic to PFC

Slide 31

Unknown For bookkeeping purposes Riparian-wetland territories that need adequate data to make any type of assurance Has not been gone to

Slide 32

Areas that are unmistakably not giving sufficient vegetation, landform, or substantial woody material

Slide 33

A current ascribe makes them powerless to corruption amid high-stream occasions, for example, the 5-, 10-and 20-year occasions

Slide 34

Adequate vegetation, landform or huge woody material present

Slide 36

PFC Assessment Procedure A. Audit Existing Documents B. Dissect the Definition of PFC C. Evaluate Functionality utilizing an ID Team

Slide 37

A. Audit Existing Documents

Slide 38

Dissipate stream vitality Reduce disintegration Filter residue Capture bedload Aid floodplain advancement Improve floodwater maintenance and groundwater revive Develop root masses that balance out stream banks Increased water quality and amount Diverse ponding and channel attributes Habitat for fish and untamed life Greater biodiversity B. Break down the Definition of PFC Adequate vegetation, landform or huge woody material to: To Yield Physics Values

Slide 39

C. Survey Functionality utilizing an ID Team 1. Stratification 2. Characteristics & Processes 3. Potential & Capability 4. Working Condition

Slide 40

Assess Functionality utilizing an ID Team 1. Stratification 1 2 3 Stream arrange Valley base sort Stream sort (Rosgen) Management/landowner change Reference or correlation destinations

Slide 41

2. Characteristics & Processes Lotic Example from Great Basin

Slide 42

2. Properties & Processes Lentic Example from Alaska

Slide 43

3. Deciding Potential & Capability Relic zones (jam, exclosures and so on.) Historic photographs, overview notes, reports Species records – creatures & plants Soils & Hydrology Ecological site characterizations Identify major landforms Look for constraining elements, both human-brought on and characteristic, and figure out whether they can be revised Experienced ID Team (Hydrology, Soils, Vegetation, Biology)

Slide 44

4. Working Condition The state of the whole watershed/catchment is vital

Slide 45

Area Shape Orientation Geology Elevation Climate 4. Working Condition Fixed Catchment/Watershed Variables

Slide 46

4. Working Condition Management Influenced Catchment/Watershed Variables Impervious Area Soils Drainage Density Vegetation Channel Features

Slide 47

4. Working Condition Some riparian-wetland regions can work appropriately before they accomplish their potential.

Slide 48

4. Working Condition Others may require the potential vegetation to work.

Slide 49

4. Working Condition State E State D State C State B PFC State A

Slide 50

IDT and Community Working Through the PFC Assessment Helps Determine Potential & Capability How well physical procedures are functioning How well withstand energies of high-stream occasions like 5-, 10-, and 20-year occasions
