Vegetation - Pinnacles National Monument [ds947] GIS Dataset

Introduction: AIS was contracted by NPS to photo interpret and map a vegetation database for Pinnacles National Monument (PINN) using the National Vegetation Classification System (NVCS). The mapping project was initiated in 2007 and was completed in 2009. For the complete description of the project please refer to the Vegetation Classification and Mapping Project Report, Pinnacles National Monument (Kittel, et. al., 2009). The study area for the project covers 44,997 acres and consists of two tiers. The first tier (park and buffer area) includes lands within the park boundary as well as a quarter-mile buffer around the park. The second tier (extended study area) includes several areas of interest, of varying sizes, adjacent to the park and buffer. The base imagery for the mapping was the 2005 NAIP natural color (leaf-on) digital orthophotos, with supplementary 2003 natural color digital orthophotos (leaf-on) and 2002 color infrared digital orthophotos (leaf-on). The Original mapping was done using an on-screen photo interpretation and digitizing method. Field reconnaissance was conducted before the mapping, and an in-field map and vegetion key validation was conducted, with resulting field revisions incorporated. The original mapping classification contained mainly alliance and association level classes, as well as group and macrogroup categories such as xeric chaparral, mesic chaparral, riparian trees, riparian shrubs, wet herbaceous, and dry herbaceous. There were also mapping unit classes such as rock outcrop, post burn chaparral, built-up, agriculture, and planted trees and shrubs. Land use was a second layer in the database, which included park facilities. Refer to Vegetation Classification and Mapping Project Report, Pinnacles National Monument, (Kittel, et. al.,2009) for the full original mapping classification. The complete report for this dataset is avaliable here: https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=18212 . The three deliverable databases to the Park are described below: " Original Database - This is the pre-AA vegetation map database that was delivered in February 2008, as an interim product. This database has no modifications as a result of AA. The original database may have some useful information that the other databases will not have. It is recommended to archive the original database, but it is available when needed. There is no documentation to accompany the original database. " Post AA Database - This database represents the modifications to the vegetation database as a result of AA. Changes are in the form of global recoding reflecting bumping up to higher hierarchical categories for most types that were <80% producer accuracy. The purpose is to have a database with as many types >80% producer accuracy as possible. Some types with accuracy 70-80% were left in as agreed to by the Park. This is the peer reviewed official database. The documentation in Vegetation Classification and Mapping Project Report, Pinnacles National Monument (Kittel, et. al., 2009) is for the Post AA Database, delivered in July 2009. Note that AA only applied to land within the park boundary and quarter mile buffer. " Post AA Park-Specific Database - This can be considered a final working vegetation database in which polygons for selected types that are <80% producer accuracy have been revisited and reviewed for linework and/or coding in order to improve the interpretations of the type based on information gained from the AA process. In order to assess the accuracy of this database a new AA effort would need to be conducted. In theory accuracy is improved, though not assessed, by applying information learned through the AA process. This document is provided to accompany the Post AA Park-Specific database. Descriptions have been modified in some cases to better reflect the mapping as a result of accuracy assessment information. Types above 60% were kept. If the total polygon count for a type was <30 then all polygons were revisited and recoded as needed. If the polygon count was >30 then a limited criteria such as low conifer density or low tree density were used for revisiting and recoding. In other cases a description modification was necessary. Refer to the Classification Modification Summary for the Post AA Park-Specific Vegetation Database (below) for a list of the changes made for each type. Vegetation Classification vs. Mapping Classification: It is important for the user to understand the difference between the vegetation classification and the mapping classification. Vegetation classification is based on analylsis of detailed field information from Releve and Rapid Assessment Plots (RA) that describe types based not only on the overstory, but on understory and vegetation species composition and cover, as well as environmental factors. The sampling effort is constrained by accessibility, logistics, and budget. Types may be missed, over sampled, undersampled, or auto correlated. Many of the components describing the vegetation type are not visible from above and therefore cannot be ascertained through photo interpretation or remote sensing techniques. The mapping classification, although attempting to mimic the vegetation classification, can only take into account visible parameters. Visible factors include overstory vegetation, understory vegetation where the overstory is open to sparse allowing a visible understory, environmental setting (aspect, elevation, slope shape, slope position, slope steepness, local geomorphology, moisture, and proximity to water). Some vegetation classes are not mappable due to consistently small size less than the minimum mapping unit, and some due to limitations in the imagery. In mapping the mapper has to put a boundary around each vegetation stand and classify each stand as a type based on the definitions and descriptions from the vegetation classification. In the process, the mapper may encounter gaps in the vegetation classification, or wide variations in the expression of a type, and gradations or transitions of one type to another. Therefore, the mapping classification description describes the vegetation or mapping classes from a photo interpretation and mapping perspective. Mapping classes that do not correlate directly to the macrogroup, group, alliance, or association of the vegetation classification are called suballiance or superalliance "Mapping Units". The mapping unit is a mapping class that is a mappable type as viewed on the imagery that maintains consistent floristic and/or ecological relationships. If not for the mapping unit, the type would be backed off to an alliance, group, or even macrogroup level. Chronology: The following section is a short outline, listed in chronological order, of the vegetation mapping effort at Pinnacles National Monument (PINN). 2003 -- 256 relev plots were collected within the Monument following California Native Plant Society protocols 2004 -- an additional 335 relevs were collected on portions of the 2,000 acres of land that previously comprised the Kingman Ranch and is now held by The Nature Conservancy for NPS purchase. Additional relev data were collected to capture vegetation types not sampled in 2003. University of Montana conducted mapping with Landsat imagery. 2005 -- University of Montana, Wildlife Spatial Analysis Lab completed a vegetation map with 11 classes 2006 -- Park acquires more funding to complete vegetation association classification and a more detailed map. California Native Plant Society (CNPS) and NatureServe are contracted to conduct vegetation classification and plant association descriptions. AIS is contracted to produce a more detailed map of the current vegetation. Fall 2006, winter 2007 Vegetation analysis and classification gets under way. 2007 March-- Initial Meeting and Park Tour, Preliminary photo interpretation mapping classification compiled. May-- First photo interpretation field reconnaissance June-- Second photo interpretation field reconnaissance August-- Begin photo interpretation, mapping and quality control of vegetation delineations and attribution. October-- First field verification November --Second field verification.

Completion of photo interpretation, mapping and quality control of vegetation delineations and attribution. July -September Field crew training by CNPS, NatureServe and AIS, and field work conducted to collect AA points. September -December AA data entered into database. 2009 January-February AA data analyzed, map validation, AA statistics generated and final map production. March-June-- Final report production and map printing Post AA Park-Specific Database Mapping Descriptions: The mapping descriptions characterize the mapping classes used in the Pinnacles National Monument vegetation map that was compiled in 2007-08. The descriptions are based on field reconnaissance, releve field samples, and 2005 NAIP natural color imagery. Other supplemental imagery may be applicable where noted. Each mapped class is presented with the following format: " The top of each page lists the Map Code with the Common Name of the map class, followed by the Scientific Name of the map class. " Any vegetation classification associations that nest hierarchically into the map class are listed next. " A snapshot of the vegetation map showing an example mapped polygon of the map class draped over the NAIP aerial imagery. " A map showing the distribution of the map class in the original database over the study area. The inner boundary shown is the park boundary. " A brief description of the map class describing general structure, cover, species, and ecology. Also noted is whether the map class is mapped within the park and buffer, expanded study area, or both. " A brief description of the photo signature for the map class. " A list of other map classes which are similar in signature to the map class being described. Dominance and percent cover terms used in these descriptions are represented as follows (values are approximate): Overall Structural Density: >60% Dense or continuous 40-60% Intermittent or slightly open 25-40% Open 10-25% Sparse <10% Very sparse <5% Very Low, or can be present Individual Species: >60% Extremely High 40-60% Very High 25-40% High 10-25% Moderate 5-10% Low, for trees this can be emergent 1210 - Foothill Pine Woodland Alliance (Included in the Original, Post AA, and Post AA Park-Specific databases) Pinus sabiniana Woodland Alliance Pinus sabiniana/Ceanothus cuneatus-Rhamnus ilicifolia Woodland Association Pinus sabiniana/Eriogonum fasciculatum Woodland Association Aerial Photo Mapped Unit Distribution A Description: The Pinus sabiniana Woodland Alliance is mapped as intermittent to sparse stands of trees over an understory of intermittent to sparse chaparral, coastal sage scrub, grass, and/or rock.

Riparian or mesic shrubs, including Salix lasiolepis, Baccharis salicifolia, Baccharis pilularis, Toxicodendron diversilobum, and Rosa californica may be present, each at high to very low cover. This type favors riparian corridors along perennial streams on major flat floodplains. The trees usually occupy the stream channel edge or are within the active floodplain. Platanus racemosa is common in the Bear Gulch and South Wilderness Chalone Creek areas. Populus fremontii is common in Bear Valley and in the South Wilderness Chalone Creek areas. Quercus lobata is common in the Bear Valley area. This class is mapped within the park, buffer, and expanded study area. Photo Signature: The trees are usually clustered together with no clear indication of individuals. Salix laevigata and Populus fremontii both appear as dull green with a large, irregularly shaped, dense crown. Due to the similarity of signature, they are very difficult to discern from each other. Platanus racemosa also has a similar signature as Salix laevigata and Populus fremontii. However, Platanus racemosa is usually taller than the other trees in the canopy. It also has a more open crown and occurs as individuals. Quercus agrifolia is more discernible on the imagery. It is dark green in color with a coarse texture, and a rounded billowy crown. Individuals can be seen among the other riparian trees. Quercus lobata is dull to dark green with a large rounded crown containing many small openings.

The 2003 and 2004 Park crews were Sherry Bottoms, Katie deLaveaga, Shauna Hee, Michelle Karle, Kipp Marzullo, Keir Morse, Kendra Moseley (NPS) and others not listed here. Gwen Kittel of NatureServe conducted quantitative analyses and prepared the preliminary vegetation classification; analysis results were reviewed and final association names assigned by Julie Evens (CNPS) and Gwen Kittel (NatureServe). The California Native Plant Society staff, including Ed Kentner, created the local association descriptions. Ed Reyes and Arin Glass (AIS) conducted the photo interpretation and Debbie Johnson, Ed Reyes, Mike Nelson and Ben Johnson conducted the accuracy assessment. Jennifer Buck (CNPS) assisted with accuracy assessment analysis. All parties contributed to the final report. Ben Johnson of AIS also created most of the report figures. Thanks also to John Menke (AIS) and Todd Keeler-Wolf (California Department of Fish and Game) for their guidance during the initial meeting and field reconnaissance. Special thanks to Sharon Franklet, Jason Herynk, Denise Louise, Brent Johnson, Valerie Nuttman, Paul Johnson, Eric Brunnermann, Darrell Chambers, Leticia Ruiz, Lisa Smith, and the Condor Program Team of Pinnacles National Monument, who made us welcome whenever we arrived to check the map or collect field data, and provided helpful advice, keys, access and field assistance to help us best access different parts of the Monument. For these and other contributors to the success of the project, we are grateful.
