Abstract:
This project, which was funded by the Joint Fire Science Program (JFSP), measured the 20+ year post-fire response of vegetation and fuels on a restoration experiment in a ponderosa pine-bunchgrass ecosystem on the Fort Valley Experimental Forest (FVEF) G.A. Pearson Natural Area (GAPNA) near Flagstaff, AZ. In 1992, this replicated experiment was established within an old-growth ponderosa pine forest to evaluate the long-term ecosystem responses of an untreated control and two restoration treatments, which were thinning from below and thinning from below plus prescribed burning. Specifically, we quantified changes in key response variables related to post-fire fuels and plant succession in southwestern ponderosa pine, such as pre- and post-settlement tree structure, understory herbaceous cover and diversity, and surface fuels. We examined the interaction of prescribed fire and drought on tree growth and mortality, herbaceous abundance and diversity over this 28-year period. This data publication includes measurements from 1992-2019 of tree overstory species, tree diameter and tree condition class, herbaceous cover and standing crop by species, forest fuels (Brown transects) for litter plus 1-hour, 10-hour, 100-hour, and 1000 hour fuels. Lastly, this publication also includes high resolution images of the FVEF GAPNA for all pre- and post-burn plots taken in 1992 and 1995-2019.
Purpose:
In 1992, this replicated experiment was established to evaluate the long-term ecosystem responses of an untreated control and two restoration treatments: 1) thinning from below and 2) thinning from below with prescribed burning. In 2015, we received a Joint Fire Science grant to quantify changes in key response variables related to post-fire fuels and plant succession in southwestern ponderosa pine, such as pre- and post-settlement tree structure, understory herbaceous cover and diversity, and surface fuels.

Tree diameter data and fuels data were measure to the nearest 0.1 cm.
Completeness_Report:
Photographs were taken in 1992 during pre-treatment and repeat photographs were taken after tree thinning from 1995-2019.

The tabular data contain blank values, which are missing data. Values of -999 were recorded for tree diameters at breast height (dbh) if the tree was forked. If a tree was forked, -999 goes into the dbh field, and the multiple dbh values are recorded in the comment field. For tree ages, values of -999 are also recorded when it was impossible to estimate the number of tree rings to pith.

STUDY DESIGN

This study took place in an old-growth ponderosa pine-bunchgrass ecosystem on the Fort Valley Experimental Forest (FVEF) near Flagstaff, AZ in a 4.3 ha decommissioned portion of the G.A. Pearson Natural area. In 1992, five 0.2 to 0.3-ha whole plots were established in each of three treatments: 1) thinning from below (thin only), 2) thinning from below plus forest floor manipulation with periodic prescribed burning (thin and burn), and 3) control. The five control treatment plots were located non-randomly on one side of the study site, while the thinning and composite treatment plots were assigned randomly. This design was necessary so that the fuel break created by the treated plots would protect the FVEF historic buildings. Treatments began in the winter of 1993. Covington et al. (1997) provide more details regarding these treatments.

We provide additional information on the research site grid system, plots and subplots in \Supplements\Fig1_FVEF_GAPNA_map_1992gridlines.pdf and \Supplements\Fig2_FVEF_GAPNA_map_EcolRestorationTrts.pdf. The 1992 grid system is overlain on the original FVEF 1920 S6A study.


DATA COLLECTION

1) Tree Overstory (Tree Structure):
During 2014 and 2015, we collected tree size and condition class. During the fall of 2016, we extracted tree cores for all trees (≥ 2.54 centimeters [cm] at diameter at breast height [dbh]) in the two treated areas (thin only and thin plus prescribed burn), plus we collected a subset (2.5% random sample) of tree sizes and cores in the control treatment. All trees remeasured in 2014 and 2015 were retagged, if needed. All data were recorded electronically for subplots 1-3 (on field computers) and on paper data sheets for subplots 4-17 and entered in a MS Access database. Tree size structure were summarized for each treatment, expanded to a per area basis, and tested for statistical significance among treatments.

A total of 627 cores were extracted. It is worth noting that we attempted to collect cores from the same trees sampled in 2006 (10 years earlier), but due to overstory mortality of 59 trees, we collected 627 cores (instead of the 686 cores originally collected in 2006). These tree cores were taken to the NAU ERI lab, mounted and sanded, cross-dated and tree ring widths measured to relate tree growth as a function of restoration treatment and weather over the past 20 years.


2) Herbaceous Cover and Production (Understory):
We measured herbaceous plant cover, composition and species richness (two, 1-meter² quadrats [0.5 x 2 meter] per subplot; n=110) by treatment and patch type (presettlement group, remnant grass opening, etc.) between 1992 and 2019. We measured herbaceous plant production (biomass; clipped and weighed) by species every four years: 1992 (pretreatment), 1993-1996, 1998, 2002, 2006, 2010, 2014, and 2018). (See Moore et al. 2006, Laughlin et al. 2006, Laughlin et al. 2008, and Laughlin et al. 2017 for herbaceous sampling details by treatment, patch type, and species composition, respectively).


3) Surface Fuels:
We measured surface fuels (two Brown’s transects per subplot; n=110) between 1992 and 2019. Measurements include 1-hour (hr), 10-hr, and 100-hr as well as litter and duff depths along 5 meter fuel transects per subplot. Data were recorded in 1992 (pretreatment), 1994, 1996, 1997, 1998, 2002, 2004, 2006, 2010, 2014-2019. Data for sound and rotten fuels (diameter, location, and length) were also recorded for the same time period.


4) Repeat Photographs

Starting in 1992 photographs were taken at each of 31 different photo point locations, and these images represent pre-treatment conditions. Photos were then taken annually at these same subplot centers from 1995-2019, in early autumn (September-October) at the same photo points. See Covington et al. (1997).

There are four photo points that are located on the boundary between the control and treated areas. These four photo points (263, 272, 273, and 291) each have four photos taken in the control (“A, B, C, and D”) and four photos taken in the treatment (“E, F, G, and H”). The photo point map (\Supplements\FVEF_GAPNA_photopoints_map.pdf) and photo point locations template (\Supplements\FVEF_GAPNA_photopoint_locations_template.pdf) show the location of each photo point. Note that there are two blue dots in each square labeled 263, 272, 273, and 291, one in the control and one in the treatment. These four photo points continued to have eight photos each from 1999 forward, but the photos are instead labeled “GPNA99263C050.jpg” or “GPNA99263T006.jpg” for example, indicating the site, year, photo point, treatment, and azimuth (direction of photo view) in the file name.

PHOTOGRAPHS

1992-1998:
\Data\FVEF_GAPNA_site_photos\YYYY\GPYY###X.TIF: TIF image files (124 per year) containing high resolution Fort Valley Experimental Forest G.A. Pearson Natural Area (FVEF GAPNA) photographs, showing pre- and post-burn plots between 1992 and 1998 (YYYY). Photos were taken with 35 millimeter camera, converted to slides and then scanned at 600 dots per inch (dpi) as TIF. The A, B, C and D photographs are taken from plot center. Repeat photographs were taken at 90 degree increments from each other, all A-D (and E-H photos for photo points 263, 272, 273, nor 291). Original photographs in 1992 were taken facing random azimuths, not cardinal directions, then, repeat photographs were taken from the same 1992 locations (from 1992-1998 and 1999-2019).

Filenames are comprised of:
“GP” = 2-letter site code, followed by
YY = 2-digit year of capture (YY), followed by
### = 3-digit grid number, and ending in
* = A, B, C or D (or E-H for a few photo points).


1999-2019:
\Data\FVEF_GAPNA_site_photos\YYYY\GPNAYY###*.JPG: JPEG image files (124 per year) containing high resolution FVEF GAPNA photographs, showing pre- and post-burn plots between 1999 and 2019 (YYYY). Photographs were taken in born-digital format at the highest available resolution at the time of capture. (Photo azimuths are indicated in the 1999-2019 file formats and also shown in \Supplements\FVEF_GAPNA_photopoint_locations_template.pdf.)

Filenames are comprised of:
“GPNA” = 4-letter site code, followed by
YY = 2-digit year of capture, followed by
### = 3-digit grid number, followed by
“T” (treated) or “C”(control), and
* = azimuth of that photo.
