Riparian samplingPREPARATIONDatasheet packets:Each lake has 8 survey sites.One packet per site:3 10m x 10m riparian zone plot data sheets1 Sapling plot or General Site Info data sheetFor 2 of the 8 sites, packets will need to include 2 riparian subzone data sheets.Weather can be highly variable. Data sheets should be printed on write in rain paper.Survey site selections:8 Sites per lake will be selected using GIS software.Subzones: To look at the effects of wind, sun, and fetch; select 2 of the 8 sites for additional subzone surveys. One site must be located in the NW quarter of the lake and the other in the SE. Within each of these 2 chosen sites, randomly select a 10m x 10m subzone plot in zone 2 and another 10m x 10m subzone plot in zone 3. (See figure 1).Sapling plots: At each site, two 5m x 5m sapling plots should be randomly selected within plots A, C, andoror E (Refer to figure 3).EQUIPMENT LISTClipboard, data sheet packets, lake and site maps, pencils, watch, compass, 50m measuring tapes, Diameter tapes (fabric and combination tapes), flagging, GPS unit,Oars, cushions and vests, motor, gas. Appropriate rain gear and boots.FIELD DATA COLLECTIONRecord the lake name, site number, plot number, date, observers, start and stop time.Collect a GPS point at the start of each of the 8 survey sites (plot A).timesIf the site has to be relocated due to denied permissions, mark new location on lake maps.Prepare Survey Plots:Each site is 30m x 50m in size. Five 10mx10m plots along shoreline are the zone 1 survey plots. Subzones are located in Zones 2 and 3. Plots should never overlap.Set up plots (A, C, E)Facing the selected site location (looking from the water towards shore), plot A is on the left, C and E are to the right of A respectively.Mark the sites starting point (with a flag and a GPS point). Using a meter tape to place flags at 10m increments along the shorelines ordinary high water mark (0m, 10m, 20m, 30m, 40m, 50m).For each 10x10 plot, determine the shoreline aspect, then use a compass and meter tape to place corner flags back 10 meters from shore so that each plot is square.Record the slope and aspect (perpendicular to shore) for the start of plots A, C, and E. This will represent the hills steepness and direction.Recording Data:General site info:Site information must be recorded for all 5 plots (A, B, C, D, and E)Record ownership (public or private).List the number of docks and buildings –count them only once if they cross into 2 plots.Presenceorabsence information – Using the list provided, check anything that is present, or list it as other. Record what is dominant. There are 2 parts to the General site info list:Qualitative assessment of habitat (forest stands, herbaceous, wetlands, etc).Human development andoror disturbance.FOR PLOTS A, C, and E:Live Trees:Record the species and diameter at breast height (DBH) for every living tree that is larger or equal to 5cm DBH (other woody plants having a greater than or equal to 5cm DBH should also be recorded).Diameter at breast height: Since trees are swelled at the base, measurements are made 4.5 feet (1.37 meters) above the ground in order to give an average diameter estimate.Trees on plot edge: Sometimes trees will be questionable as to whether they are in or out of the plot. Good rule of thumb is a 50percent cut off. If the tree is more than 50percent within the plot, count it. Do not count 1 tree in more than one plot!Standing snags: A snag is a (or part of a) dead standing tree taller than 1.37 meters (DBH). If a snag is greater than or equal to 10cm DBH then record type (snag), type of break (natural, un-natural, beaver), species (if known), DBH, and branchiness (0-3).Stumps: A stump is dead tree cut or broken off below 1.37 meters (DBH). Record stumps that are greater than or equal to 10cm in diameter. Take the diameter at the base of the stump but above the root mass. Record type (stump), type of break (natural, un-natural, beaver), species (if known), and diameter at base. Branchiness is assumed to be 0.Coarse Woody Debris (CWD) in Riparian zone:For this study, CWD is considered any logs greater than or equal to 10cm in diameter and greater than or equal to 150cm in length.Record type (log) and type of break (natural, un-natural, beaver, unknown). Record the species type (species, conifer, hardwood, or unknown), the diameter at base, and log length from base to longest branch tip.Record Branchiness (0-3). Where 0 is no branches, 1 is few, 2 is moderate, and 3 is many branches.Record Decay (0-5). Where 0 is a live tree touching the ground at two or more points, 1 is recent downwood (e.g. lacking litter or moss cover), 2 is downwood with litterorhumus or moss cover; bark sound, 3 is bark sloughing from wood; wood still sound, 4 is downwood mostly barkless; staubs loosening; wood beginning to decay; logs becoming oval and in contact with the ground along most of their length, and 5 is decay advanced; pieces of wood blocky and softened; logs becoming elliptically compressed. timestimes NOTE: paper birch retains its bark long after the wood has rotted, score logs of this species by the softness of the wood, not the presenceorabsence of bark. timestimesAdditional parameters:If a log extends out of a plot, record its entire length and measure diameter at the base regardless of whether the base is inside or outside of the plot.If a log crosses into more than one plot, record the entire length and measure diameter at the base, but record log only in the plot where the base is (if the base is outside of the site, then record in the plot closest to the base).Paper birch: often are broken into many small parts. If segments are still in line (no more than ~5 cm separating them), then you can count breaks as a single log.Logs that extend over the water are measured only from the base to the shoreline and listed in notes as measured to water.For each site, Two 5m x 5m sapling plots are randomly selected in plots A, C, andoror E. Use the numbering scheme depicted in graphic.Use compass and meter tape to setup and mark square plots using the original plot aspect.For each sapling plot, count and record all tree saplings greater than 30 centimeters in height but having less than a 5 cm DBH.Subzones:Subzone plot data are recorded the same as plot data.Refer to figure 1 to set up random subplots at 2 of the 8 sites at a lake. Use compass and meter tape to setup and mark square subplots. Use the original plot aspect when possible.For each square 10m x 10m subplot (one in zone 2 and one in zone 3) record slope and aspect.Record all live trees that have greater than or equal to 5cm DBH. Record all stumps greater than or equal to 10cm DBH and snags greater than or equal to 10cm diameter at base. Record logs greater than or equal to 10cm in diameter and greater than or equal to 150cm in length.
