& Management / Mammal
Husbandry and Management / Techniques:
||A hammock made from
cloth-covered fire hose, which is sufficiently durable to withstand the
sharp claws of bears for some time.
To make a 5 ft (1.52 m) diameter hammock:
- Place 15 strips of hose, each 80 inches (203 cm) long, side by side
(no spaces between strips).
- Weave a further 15 strips of hose in and out of these at
right-angles to the original strips of hose.
- As each strip is woven in, push it up as close as possible to
the previous strip.
- Alternate each strip so that if one goes under the first of the
original strips, the next goes on top, etc.
- Leave about 10 inches (25 cm) of each strip of hose unwoven on each
- Connect the edges around a rope:
- Using a strong rope of e.g. 15 ft (4.6 m) long (the exact length
will depend on where the hammock will be positioned), fold each
hose end over the rope and fasten back to itself with two 1.5 inch
bolts per hose end, placing a washer on each side - under the bolt
head and under the nut.
- Pop rivets could be used but bears are more likely to
pry the hose loose over the rivets.
- Using the ropes, attach the hammocks to suitable sites in the
enclosure, such as slung between parts of a climbing structure.
|Appropriate Use (?)
- May be very popular with bears.
- Fire hose is heavy.
|Complications/ Limitations / Risk
- Materials must be sufficiently strong to take the weight of the
- If fasteners are not chosen carefully the bears may pull them
through the hose, unpicking the construction. (N19.6.w1)
|Equipment / Chemicals required and Suppliers
|Expertise level / Ease of Use
- Cost will depend on whether materials are donated (old fire
hose/cut-offs) or need to be purchased.
|Legal and Ethical Considerations
- To minimise the risk of
injury to the bears, materials used must be sufficiently strong to take the weight of the
bears and construction methods should aim to prevent bears from
dismantling the structure (e.g. use of bolts, nuts and washers, rather
