BTW the Gondwanaland garden is on the south side of my house and it definitely cools the entrance and lower floor. Natural Air conditioning, at least while this ferny glade restrains some of its natural humidity.

Admittedly the weather has been very kind, lots of rain, but i am impressed with how fast the ferns have recovered from the drought conditions of the past few years.

Not many gardens boost works of art these days, but Gondwanaland has a new wall hanging. It’s one of the rock panels from my “Retracing Darwin” exhibition fitted out as the new home for an stag horn fern [Platycerium]. The fern is “growing” over my representation of the geological layers representing the Permian mass extinction event. A somewhat poignant reminder of the larger cycles in nature.
I think it looks perfectly at home.

It is amazing how the ferns have come to life. Everything is gushingly green again

My Wollemi pine, is having a vacation. It is part of my Retracing Darwin exhibition down at the Gecko Gallery Studio at Fish creek, That’s the pine in a pot down in the corner amongst the things Charles Darwin didn’t see or describe, when he travelled from Sydney to Bathurst in 1836. From Govert’s Leap Darwin did look out down into the Wollemi national Park. Instead he just complained -
16th. Everywhere we have an open woodland, the ground being partially covered with a most thin pasture. The trees nearly all belong to one family;1 & have the surface of their leaves placed in a vertical instead of as in Europe a nearly horizontal position; This fact & their scantiness makes the woods light & shadowless; although under the scorching sun of the summer this is a loss of comfort, it is of importance to the farmer, as it allows grass to grow where it otherwise could not. — …. It is singular that the bark of some kinds annually falls, or hangs dead in long shreds, which swing about with the wind; & hence the woods appear desolate & untidy. — Nowhere is there an appearance of verdure or fertility, but rather that of arid sterility: — I cannot imagine a more complete contrast

My wollemi pine gets its anuual-ish repoting. Compared with other pines here in victoria it is looking healthy with some new growth visiable (probably related to the fact that i still "hand" water it by placing it in a bucket of shower water regularly). However it is starting to look just a little spindly and I am wondering if it is a good idea to prune and if so when? Checking the wollemi website suggests shaping is a good idea and anytime of the year, but sterile secateurs!

Swalim (the Somalia Water & Land information Management) project has put their comprehensive Rainfall Observers Manual on the net.
The rain gauges that come in most weather station kits are based on tipping buckets. These are generally not as accurate at the conventional graduated cylindrical collectors, for a couple of reasons. A certain amount of rain is needed to tip the buckets and the rain event may finish before the bucket is tipped, where the rainfall is infrequent and low this can be an issue. Also the tripping mechanism may have considerable tolerance (most are made of molded plastic) and it may be wise to "calibrate" the readings against a convention gauge (using a few decent rain events of perhaps 2mm of more)
