Forestry Tools

• Ecology
• Springport High School

2
Altimeter

• Measures height of trees and can also be used to
  measure slope.

3
Back Pack Fire Pump

• When filled with water, this hand-operated pump
  can be used to extinguish small areas of burning
  grass.

4
Bark Gauge

• Measures bark thickness by driving the cutting
  edge through bark until wood is reached. Guard is
  slid against tree or log and bark thickness is
  read directly off the scale.

5
Cant Hook

• Used to roll and position logs.

6
Chainsaw

• Used to fell trees, prune branches, and cut up
  logs.

7
Chainsaw Chaps

• Made with specially woven fibers designed to
  burst apart upon contact with a chain saw chain
  and jam the chain against the saws bar and
  sprocket, protecting the users legs from injury.

8
Clinometer

• Used to measure heights of trees, slopes, and
  vertical angles.

9
Data Recorder

• Used to electronically store data in the field
  for transfer to a computer back in the office.

10
Desiometer

• Used to help estimate the spacing of trees and
  determine if thinning or other practices are
  needed.

11
Diameter Tape

• When wrapped around the trunk of a tree, provides
  readings of trees diameter (Dcircumference/pi).

12
Dot Grid

• Used to calculate acreage by dot count on any map
  or photo, regardless of the scale.

13
Drip Torch

• Used to widen fuelbreaks by burning out fuels
  between the break and the oncoming fire. It is
  widely used in mop-up operations to burn out
  pockets of fuel remaining adjacent to control
  lines after a wildfire is contained. It is also
  used to ignite fuels as part of a prescribed
  burn.

14
Fiberglass Measuring Tape

• Used to measure distance in meters or feet does
  not automatically retract like a logger's tape.

15
Fire Rake

• Used for raking fire lines to mineral soil,
  digging, rolling burning logs and cutting grass,
  small brush or saplings.

16
Fire Weather Kit (Belt Weather Kit)

• Used to measure wind speed and direction,
  humidity, and temperature. It is often worn on a
  belt.

17
Fire Swatter (Fire Flap)

• For smothering fires in grass, straw and low
  weeds. Sliding the swatter over low flames will
  extinguish the fire without fanning the blaze or
  spreading sparks.

18
Flow/Current Meter

• Used to determine water velocity in streams.

19
GPS Receiver

• Utilizes orbiting satellites to determine exact
  latitude/longitude position. This information is
  used to draw maps and measure acreage as well as
  aiding in navigation.

20
Hand Compass

• Used to navigate to known locations and to
  determine ones location.

21
Hand Lens/Field Microscope

• Used to help identify items in the field.

22
Hip Chain

• Used to measure distance by tying the end of the
  string to an object and walking. Distance
  displays in meters or feet on an odometer inside
  the box.

23
Hypo-Hatchet

• Used to selectively kill undesirable trees in a
  forest stand without harming desirable trees
  nearby by injecting tree with herbicide.

24
Increment Borer

• Used to extract cores of wood from trees or
  freshly treated poles, piling, lumber, or timbers
  to determine growth rate, age, tree soundness and
  chemical penetration by drilling into the tree or
  material and extracting the core.

25
Log Rule

• Used to measure logs and determine board foot
  volume. The three most common log rules (ways of
  estimating log or tree volume) are shown on these
  devices.

26
Loggers Tape

• Used to measure tree diameter as well as ground
  distance recoils back into case when released.

27
PH Meter

• Used to determine the pH (how acidic or basic a
  substance is).

28
Planimeter

• Used to determine acreage from aerial photo or
  map. The round part is rotated over the perimeter
  of the area being measured. Readings in acres are
  displayed.

29
Plant Press

• Used to flatten leaves and other plant parts for
  reservation as part of a collection.

30
Plastic Flagging

• Used to mark utility line locations, plot
  corners, etc.

31
Pulaski Forester Axe

• Combination grub hoe/axe. Designed for chopping,
  grubbing, and digging fire lines in brush-filled
  or rocky terrain. Also is used for trail
  construction and maintenance.

32
Relaskop

• Used to measure tree height, diameter, and basal
  area (a measure of tree spacing) has a variety
  of scales.

33
Safety Glasses

• Protects wearers eyes while working in
  conditions where airborne particles are likely.

34
Safety Hard Hat

• Protects wearers head from falling material.

35
Soil Sampler (Soil Probe)

• Used to remove cylindrical cores of soil to
  determine soil type and other soil attributes.

36
Soil Test Kit

• Used to determine soil properties such as pH and
  the relative abundance of various minerals.

37
Staff Compass

• Used in surveying - much more accurate than a
  hand compass, but less accurate than GPS survey
  units.

38
Stereoscope

• Used to observe and measure slope on aerial
  photos.

39
Survey Instrument

• Used to determine slope.

40
Tally Book

• Use in cruising timber or in tallying lumber -
  height, diameter, and number of trees are
  recorded when cruising.

41
Tally Meter

• Used in cruising, tree survival checks, and other
  applications where items are being counted. Fits
  in one hand and can be reset to zero by turning
  one knob.

42
Tree Caliper

• Used to measure tree diameter.

43
Tree Marking Gun

• Used to squirt paint on trees to be removed
  during thinning and other operations.

44
Tree Planting Hoe

• Used to create a slot in which to plant tree
  seedlings.

45
Tree Planting Bar

• Used to create a slot in which to plant tree
  seedlings.

46
Tree Stick

• Use to determine number of logs in a tree,
  diameter, and volume and to scale logs.

47
Water Sampler

• Used to remove a small quantity of water from a
  stream or other body of water for use in testing
  its quality.

48
Water Test Kit

• Used to determine water quality in terms of such
  measures as dissolved oxygen, temperature, pH,
  and turbidity.

49
Wedge Prism (Basal Area Prism)

• Used during cruising timber to help determine
  tree spacing as well as to decide which trees
  should be measured when sampling is being used.

50
Wheeler Caliper

• Used to measure diameter and height of trees.
