Forest Resources Information


  • Provided 198 technical assists upon request to various customers on topics of marketing, utilization, and efficiency, Best Management Practices, and forest resource and industry data.

  • Provided various training opportunities (log, lumber, tree grades, chainsaw training, etc) to 65 attendees. Those attending were a combination of professional natural resources personnel and forest industry professionals.

  • Private contractors collected forest inventory data from 251 plots across the state. The information, collected annually provides an excellent picture of the forest resource in Indiana.


Indiana State Forest Research Outline
Research designed to study different silvicultural systems and their impacts on wildlife and public perception with 4 goals:

  1. develop a proven system of forest management prescriptions to maintain desired populations of native plant and animal species and important communities such as those dominated by oak species;

  2. understand the response of targeted native wildlife and plant species to forest management, in order to identify the positive effects and mitigate the potential negative effects on species of conservation concern;

  3. assess public attitudes towards forest management to develop new approaches for education of the general public and private landowners; and to engage various interest groups in a discussion of proper land management;

  4. identify direct and indirect benefits of specific forest management practices to local and regional communities, and understand the impact of forest management practices in community development.


and specific sampling_:
Research will be carried out on 9 Management Units (MU) at two state forest properties, Morgan-Monroe and Harrison-Crawford State Forests.

3 Even-aged MUs

3 Uneven-aged MUs

3 Control MUs


Each MU is approximately 900 acres.

A central 200 acre sample unit (SU) will be sampled within each MU.


Even-aged MU

Harvest

Each even-aged SU will receive 2, 10-acre clearcuts and 2, 10-acre shelterwood cuts.




Understory Treatment

Half of each cut (5 acres) will be treated with understory manipulation within the first year following harvest. An additional 5 acre area of unharvested forest adjacent to each harvest opening will also be treated. The planned understory manipulation is prescription burns; however treatment may change as initial results of the mechanical manipulation study become available (see uneven-aged MUs).


Site selection

SUs will be stratified by aspect. Center points for six potential harvest sites will be randomly placed within the SU: 3 on SW-facing slopes, 3 on NE-facing slopes. The best two locations on each aspect will be chosen for the harvests. In order to reduce edge effects between treatments, points will be spaced with a minimum distance of 900 meters apart. Intensive vegetation and animal sampling will be concentrated within and adjacent to each harvest opening.



Uneven-aged MU

Harvest

Group and single tree selection harvest will be used across the entire SU; however one half of the SU will have the harvest delayed until understory treatments can establish an advanced population of oak seedlings.



Understory Treatments

In one half of the SU, 2-5 acre group selection harvests will be used. Following overstory harvest, several group openings and adjacent unharvested forest will be chosen for understory treatment. As with even-aged units, the planned understory treatment is prescription burns; however treatment may change as initial results of the mechanical manipulation study become available.


For the other half of the SU, group selection harvests will also be established, but the harvest will be delayed. The understory will be manipulated prior to harvest such that oak regeneration is encouraged. Within an area designated for a future group selection opening, all non-oak species less than or equal to 15 cm dbh will be removed or girdled. The overstory may be thinned in order to increase light penetration to the forest floor and decrease seed sources of non-oak species.

Site selection for vegetation and animal sampling

SUs will be split in half: one half randomly assigned to group/single tree selection, the other half to delayed harvest with understory manipulation. Two points will be randomly placed in each half of the MU following similar methods for even-aged management.


At each point, 4 nearby group openings will be selected; two will be located on upper slope positions and 2 on lower slope positions. The size of each opening will be 2-5 acres. These openings will be used for intensive vegetation and animal sampling, and their locations need to be identified prior to sampling.
Control MU

Harvest and Burn

Neither harvesting nor understory manipulation will occur in the control SUs. Areas outside the SU may be treated with single tree selection.


Site selection

Four points will be randomly placed in each management unit following the methods for even-aged management. Intensive vegetation and animal sampling will be concentrated around each point.


Two Scale Sampling Strategy
Scale 1: Landscape

Each SU will be overlaid with a 150 m x 150 m grid of points. Grid points will not be permanently marked in the field, but will have GPS coordinates assigned to them. Each SU will have approximately 35-40 points within its boundaries.


Scale 2: Site/Harvest Area

Each SU will be overlaid with a 20 m x 20 m grid of points. A subset of points located within a 20 acre area centered on each harvest area will be used for intensive site-level sampling. (see document on treatment design for details on randomly selected harvest areas.)


Vegetation Sampling

Scale 1


Each landscape scale point will be surveyed with a variable radius plot (10 BAF prism). Points that fall within an intensively sampled harvest area will not be sampled.
Scale 2

For each harvest area, twenty of the site-level points will be chosen for intensive sampling. 5 will be located in each of the 4 management regimes (harvest, no harvest, harvest+burn, no harvest+burn). The 5 points will be adjacent points along a transect that is perpendicular to the slope contour. All 20 points will be permanently staked.


Since there will be no harvest or burning at control SUs, only 5 points will be sampled at each of the intensive sampling locations in the control SUs.

Intensive sampling scheme:

Variable radius plot, 10 BAF prism OR ½ acre plot for woody vegetation >= 15 cm dbh

1/10 acre plot for woody vegetation >= 2 cm dbh and < 15 cm dbh

1/100 acre plot for herbaceous vegetation and woody vegetation < 2 cm dbh (seedlings and saplings separated by 1 m tall standard)
Bird and Small Mammal Surveys

Scale 1


Aural and visual point counts will be taken at each point twice during the field season. Points within a harvest area will not be sampled.
Scale 2

Aural and visual point counts will be taken at 5 points for each harvest area: one at the center of the harvest area, one upslope of the harvest, one downslope and 2 at the same slope position on either side of the harvest. The 4 outer points will be outside the harvested area, 50 m from its edge.


Amphibian Sampling

Scale 1


No sampling. Amphibians will not respond to treatment at the landscape level.
Scale 2

Sampling transects will be established parallel to vegetation transects (they will be at least 20 m apart). Transects will be comprised of 30 cover objects spaced 5 m apart. All cover objects will be placed in the field in early spring and checked every two weeks for amphibians. Cover objects will be removed after June 15th, or when salamander activity declines.


66 transects will be established in the following locations:

Control SU: 1 on each of 2 aspects per SU

Even-aged SU: 1 transect in each of 3 treatments of every harvest area (harvest, burn, harvest+burn)

Uneven-aged SU: 1 transect in each of 2 treatments of every harvest area (harvest, harvest+burn)


Bat Sampling

Scale 1


Two sites within each SU will be selected for sampling. The sites will be selected based on criteria that increase the probability of capturing bats (typically along streams or in upland travel corridors). Each net site will consist of 2 net sets using “high sets” employed for Indiana bats. Each site will be sampled twice during the summer, but not on consecutive days. The design will determine species presence within the SU.

Scale 2


Anabat detectors will be used to sample at the site-level. Sampling stations will be established inside, adjacent, and outside each harvest area. A sample station will consist of 2 Anabats: 1 lower unit to sample between the ground and subcanopy, the other to sample near the canopy level. Each site will be sampled twice during the season, one night each time.
Insect Sampling

Scale 1


Funnel traps, panel traps, and window traps will be established to determine the presence and abundance of wood boring beetles within each management unit. The traps will be set-up at the beginning of the field season. Insects will be collected from the traps every other week and preserved in alcohol. Samples will be taken to Purdue for identification.
