More Online Information
Note that many rare or endangered cycads are protected under various forms of legislation in Australia and internationally. The following links have been provided for general information but they (and the information contained in them) are NOT necessarily complete or up-to-date. Be sure to CHECK WITH APPROPRIATE AUTHORITIES yourself if you think such laws may affect you (including private individuals). If you're outside Qld (or trading with others outside Qld) check with relevant bodies governing those locations.
If you want to find out more about current laws concerning propagation, movement or trade in protected cycads in Qld, visit the Department of Environment and Resource Management website.

Warning: collection, propagation, movement, sale or purchase of any Australian native plant may be subject to laws and regulations.

Other laws may also apply to the treatment and movement of plant or soil material (for example, to control the spread of weeds, pests and diseases.)
Pre-colonial cycad a star of Gardens' expansion
A rare, 250 year old cycad will be one of the stars of the new Brisbane Botanic Gardens expansion at Mt Coot-tha. The 6.5m high, 2 tonne specimen came originally from Injune in SW Queensland. The cycad and 31,000 other new plants plus a new lagoon, playground, picnic facilities, and kitchen garden are a part of a major upgrade to the Gardens, the largest since it opened in 1970.

Cycad seeds may favour colony development
The large fleshy seeds of cycads suggest they are adapted for dispersal by a large animal, but no large birds or mammals today are known to routinely eat them. So how have cycads survived? Based on monitoring of Macrozamia miquelii by University of Queensland researchers, a new theory proposes that cycads' tendency to occur in well separated but dense colonies in the wild is a reflection of limited seed dispersal mechanisms and that this may actually be to the cycad's advantage. Because plants are either male or female, a lone seed dispersed far from other plants would be unlikely to reproduce. Very large but now-extinct animals might have eaten and deposited several seeds at once. The need to form colonies may have prevented cycads from evolving smaller seeds better suited to dispersal by smaller fauna.

Inland cycad not a rainforest remnant
Analysis of the MacDonnell Ranges cycad (Macrozamia macdonellii), suggests its ancestors arrived in central Australia in only the last 2 million years or so. If it had been isolated from its eastern relatives for 30 million years, as previously thought, greater divergence should have been observed. This means that the cycad is probably not a survivor of an ancient Eocene era rainforest. Source: Cycads in central Australia are not ancient relics (August 2012)
Guam cycad pollination studies
Studies of the endangered Guam cycad Cycas micronesica (locally known as Fadang) showed that plants on the windier side of the island produced fewer seeds, suggesting insects may be more important than wind for pollination. Understanding the reproduction of this threatened species may be critical to ensuring its survival.

New container for Kew veteran
One of the world's oldest pot plants - a specimen of cycad Encephalartos altensteinii collected from South Africa in the 1770s - has been repotted at the United Kingdom's Kew Gardens. With a trunk now over 4m long, great care and effort was required to lift the huge weight of this famous plant without damage. It now lives in a handcrafted mahogany box.

Cycads among additions to Townsville botanic garden
A new cycad garden and an avenue planting of 50 Kauri Pines is opening at Anderson Gardens. One of three botanic gardens in Townsville, Anderson Gardens is developing a theme of "dry tropical and native flora".
