As Mt Rogers begins to emerge from a very wet
and damp-cold winter the native wildflowers are beginning to bloom. The most
obvious blooms are from at least four species of Wattle with the early wattle
showing its creamy-yellow flowers in the middle of winter. By September the
Cootamundra wattles have lost their glory but they still attract many
insectivorous birds which come to feast on the invertebrates that prove that
the invasive wattles are good habitat. The Wattles ‘take it in turn’ to flower as
others will provide nectar and pollen as enticements to pollinators in November
and later in the summer. Later again Cockatoos and Superb Parrots will come
into the reserve to feed on the Acacias’ seedpods.
Many
native wildflowers are much smaller than people expect especially if they are
more familiar with large daisies, camellias, roses and other species from
overseas. The rainy seasons we have had have rehydrated the soils to such an
extent that native shrubs are very showy with masses of blooms even though the
individual flowers are intricate and small. Particularly at ground level wildflower
species have evolved very specialist mechanisms and structures for attracting visitors
and dusting them with pollen for transferring to other blooms.
It
may seem that there hasn't been much Landcare activity on Mt Rogers recently. Two
or three working days were cancelled due to weather. Because so many Privets, Cotoneasters
and Firethorns have been removed over 25 years, the group's land caring has increasingly
focused on herbaceous and grassy invasive species. The woody weeds reached the
reserve as berries eaten and carried in from gardens by hungry birds. The La
Nina seasons we have had mean that woody weeds still in suburbia and gardens produce
millions of berries to re-invade the ACT's reserves. We are already finding that
Privet seedlings are present under branches and trees where birds have perched
and pooed.
At
least three winter working bees were spent pulling out Euphorbia plants. These European,
green-flowered species are popular with gardeners seeking novelty, have caustic
sap and spread rapidly. We are monitoring infestations of berry-spread Honeysuckle,
Ivy and Blackberry and are on the lookout for new incursions when going
‘cross-country’.
As
last summer ended volunteers began to remove thousands of Fleabane seedheads to
prevent the seeds blowing away in the wind. We also removed the seemingly dead
stalks as buds around the roots seemed likely to reshoot in spring. Now we are
also digging up the rosettes of new Fleabane leaves as we search through the
reserve’s rank, introduced grasses in search of young Verbascum plants’
rosettes. Fleabane has its uses but is a major herbaceous invasive in
Australia’s agricultural areas. Here’s a quote from The Weed Forager’s
Handbook by Adam Grubb & Annie Raser-Rowland. “We use Fleabane …to remove fleas from our
dog. Boil large bunches [of fleabane] in
water and add the strained-off liquid to the bath when washing your canine.
Many human medicinal qualities have been attributed to it too, most widely as a
tea to treat diarrhoea.”
There
are two species of Verbascum that have invaded degraded land in the ACT region.
Thousands of the soft, hairy-leaved species of Great Mullein, Verbascum thapsus
are present on Mt Rogers. The
Landcare group has focused on removing the dried-off seedheads during several
working bees as each contains thousands of tiny seeds smaller than two joined
dots.. Verbascum detail, including the plants’ uses and the fact that the seeds
remain in the soil for years, is in this Wiki entry: https://en.wikipedia.org/wiki/Verbascum_thapsus
Sometimes Verbascum rosettes are growing
amongst the kangaroos’ preferred fodder and native Weeping Grass, Microlaena
stipoides.
Scores
of Thistles were removed to prevent further distribution of their ‘parachute’
seeds but we’re still finding ones we missed, particularly those that grew cryptically
under or up through shrubs and trees. This effort and daubing – spraying the invasive
grasses, CNG, ALG and ST, that come in on wheels feet and mowers is also an
individual effort rather than happening in a working bee session. We try to
reduce the amount of herbicides used or use them as a method of last resort. Similarly,
and we are helped by the La Nina damp soil, we apply the no dig method or
minimal digging whenever possible. Dormant seeds respond by germinating when shading
plants are removed and the soil is aerated. Digging also damages the essential
fungal and microbial networks that we are all finding out much more about.
As
the weather warms up we are already seeing more insects emerging with photos of
several interesting species of butterflies and moths already being recorded
near or on Mt Rogers. Sightings include Blue Tongue lizards which means that
Brown Snakes will also be basking to warm up or on the move through the
reserve. Be cautious with your off-leash dogs ………as the sign says:
Snakes live here.
They are not usually aggressive.
If you meet one stay calm and
back away slowly while
maintaining eye contact
If a dog is bitten Pet Ambulance can
be called 0448 789 039 or 0417 485
788
Note: They are not permitted to
administer antivenin.
The team at Canberra Snake Rescue
and Relocation will come to your
property 0405 405 304
to assist if you have reptilian
visitors.
The reserve is shared habitat.
Native wildlife, plants & rocks
are protected from interference
or removal by ACT laws.
And
as for Mt Rogers’ birds, we saw Scarlet Robins during the winter months but
they may have already moved out of the ACT. Seasonal migrants moving in as it
warms up include Cuckoos that don’t call “cuckoo”, Orioles and Noisy Friarbirds.
There have been many Grey Fantails around hawking on the wing for insects we
might disturb. The GFT’s are often part of Mixed Feeding Flocks of smaller
birds with each species seeking out preferred invertebrates or seeds in bushes,
on the ground or amongst the trees’ foliage and canopies.
If
you’re caring for young people there’s many in-nature activity ideas and nature
treasure hunts available on the Nature Play CBR website.
And
there’s the URBAN FIELD NATURALIST project site and companion book: A Guide to the creatures in your Neighbourhood.
Both are about, becoming and being naturalists; observant
people who pause, ponder, record and share experiences whilst out and about in
the nature around them.
Will
there be any fungi emerging as the soils and leaf litter layers warm up? An
inspection mirror is good for looking under toadstools without knocking them
over and magnifying glasses give intriguing views of leaves, flowers and
mini-beasts. Enjoy Sprummer!!
