  • Cumberland/Piedmont Network
  • Protocol- Vegetation Communities
  • Justification and Approach
  • The monitoring of vegetation communities is a
    combined Vital Sign that captures multiple
    high-priority interests of CUPN parks.
    Significant natural communities of interest for
    this category include grasslands, riparian areas
    and wetlands, calcareous glades, granitic domes,
    various forest types, and clifflines. The
    preservation of vegetation communities is key to
    the primary mission of all CUPN parks..
  • Monitoring Objectives (none are riparian
    specific)
  • Determine the long-term trend in spatial
    distribution of selected vegetation communities.
    (all parks)
  • Identify invasive plant species spreading into
    selected natural communities. (all Parks)
  • Determine if forest pests are spreading into
    selected vegetation communities. (all Parks)
  • Assist fire effects monitoring to determine if
    prescribed burn goals have been successful to
    reach a desired future condition. (at least 4
    parks are currently burning)

  • Northern Colorado Plateau Network
  • Protocol Integrated Riparian
  • Vital Signs
  • Riparian Plant Communities
  • Surface Water dynamics
  • Stream/wetland hydrologic function
  • Justification
  • Riparian zones are critical landscape elements
    harboring disproportional biodiversity.
    Integrated monitoring Increases understanding of
    dynamics and condition of these ecosystems of
    high management concern.
  • Monitoring Objectives
  • Assess
  • areal extent, cover, species composition and
    spatial structure of riparian vegetation
    (trees, shrubs, forbs, grasses)
  • cover of exotic plants
  • continuous stream flow/discharge
  • bank stability, stream channel morphology (of
    surveyed cross

21
Sampling approach The monitoring of riparian and
aquatic vital signs is integrated to target five
vital signs riparian vegetation structure and
composition, stream hydrologic function, ground
water dynamics, surface water dynamics, and
aquatic macro-invertebrates. Riparian and
aquatic vital signs are sampled using a
Network-based sampling method that delineates
elements of the target population as
equal-distance elements located on network
segments, and draws a probability sample with
unequal sampling probabilities and a split-panel
design. The sampling design relies on a
hierarchical process-based stream classification
system similar to that described by Montgomery
and Buffington (1998)).

reachsegment. B a GRTS sample of 30 sampling

San Francisco Bay Network Vital sign Riparian
habitat Justification Riparian habitat is
closely tied to the health of wetlands, streams
and stream fish assemblages. Characteristics of
riparian habitat structure are highly associated
with amount and type wildlife use.
Objectives Determine status and trend of
riparian habitat by measuring species
composition, habitat structure, and width along
streams in SFAN parks. Sampling design
approach To be determined. On the ground
measures to be linked with remote sensing.
Co-location with other vital signs, such as
birds, may occur.

  • Appalachian Highlands
  • Vital sign Riparian communities-Cumberlandian
    cobblebars
  • Justification
  • The cobblebar and cliffline communities of APHN
    parks represent globally imperiled communities
    that support many Federally- and state-listed T/E
    species and are potentially threatened by water
    pollution, changes in river flow, and changes in
    disturbances regimes.
  • Objectives
  • Determine how vegetation species composition and
    structure (percent cover, density) are changing
    in focal communities (cobblebars, cliffline
    communities)
  • Determine long-term trends in species composition
    and community structure (e.g., cover, density by
    height class of woody species) of cobblebar
    communities at BISO and OBRI.
  • Detect at least a 20 change in successional
    patterns based on height of woody vegetation and
    species composition in the 1-2m size class.
  • Detect a 50 change in bare (unvegetated)
    substrate, associated with recreational use.
  • Determine long-term trends in plant species
    composition and structure at selected cliffline
    sites at BISO, BLRI, and OBRI, comparing trends
    at recreational rock-climbing sites with
    unclimbed control sites.

25
Sampling approach Map the cobblebars in both
parks. Sampling units (the cobblebars) will
likely be selected using a stratified random
design, with major tributaries being assigned to
different strata according to the quality of
cobblebar habitat on each stream (mean cobblebar
size, for example). Sampling transects will be
laid out systematically on each cobblebar to
measure vegetation structure and composition. A
complete census of selected rare plants will also
be conducted at each site. A rotating panel
design will be used in order to determine status
of this community over a large spatial extent.

  • National Capital Region Network
  • Vital signs
  • Forest vegetation (including riparian)
  • Landcover
  • Justification
  • The riparian and upland forests in NCRN include
    at least 28 unique vegetation communities
    identified by NatureServe. Stressors include air
    pollution, loss of habitat due to development,
    erosion, visitor use, invasive species, and
    whitetailed deer.
  • Objectives
  • Determine long-term trends or changes in
  • species composition and community structure
    (e.g., cover, density by height class of woody
    species).
  • percent cover of native and nonnative
    herbaceous species and woody vines in natural
    vegetation communities.
  • stem density of native shrub and tree species
    in natural vegetation communities.
  • stem density of exotic and invasive shrub and
    tree species in natural vegetation communities.
  • effects of deer browse on stem density of
    seedlings, saplings, shrubs, and pole trees.
  • riparian buffers along streams in NCRN parks
  • Protocol FIA approach, remote sensing

27
  • Sonoran Desert Network
  • Vital Sign
  • Vegetation Community structure
  • Objectives
  • Determine changes in community composition and
    relative abundance of perennial species on SODN
    park lands across multiple temporal and spatial
    scales.
  • 2. Document the spatial and temporal variation in
    community composition and
  • relative abundance of perennial plant species.
  • 3. Identify long-term trends in community
    composition and relative abundance of perennial
    plant species.
  • 4. Identify other environmental variables that
    play a key role in community composition and
    dynamics.

28
Samping Approach Aquatic and riparian vital
signs monitoring will be highly integrated on
SODN parks where perennial waters exist. Several
vital signs including channel morphology, aquatic
macroinvertebrates, riparian vegetation, core
water quality parameters, water chemistry
constituents (nutrient levels, pollutant metals),
and microorganisms will be co-located. The
sampling frame for a park unit consists of all
perennial stream segments within the park unit
and a distance of 100 m upstream and downstream
of the park boundary. Sampling locations will be
selected using GRTS. A sampling reach will be
established as 40 times the wetted width of the
stream, as recommended by the EPA EMAP program
for monitoring wadeable perennial streams
(Kaufmann et al. 1999). The reach will be divided
into 10 equally-sized segments. Aquatic
macroinvertebrates will be sampled at the end of
each segment Three channel morphology
cross-sections will be located at the top of the
nearest riffle to the top, middle, and bottom of
the sampling reach. Water quality parameter
samples will be taken at the midpoint of the
reach, and a vegetation community structure plot
will be located on either bank at the midpoint of
the reach. This design results in the nesting and
co-location of seven vital signs
(Whoa dude!!)
