Wondering whether it’s wise, or legal,  to buy arum lilies from street corner vendors?

A recent joint press release issued by the City of Cape Town, CapeNature and SANBI (August 2010)

“There has been inaccurate information circulating about the sale of arum lilies, and the protection of two of the Cape’s amphibians, the arum lily frog and micro frog. A campaign urging residents not to purchase arum lilies from vendors at the side of the road seems to be gaining momentum whilst spreading inaccurate information about arum lilies and frogs. This misleading information has also gone viral, and is being spread via e-mail and social networking tools. It is important that the public understand the facts about these frogs, before making a decision on whether or not to purchase the flowers.

Correct information about arum lily frog

“The Environmental Management (ERM) Department, in conjunction with CapeNature and the South African National Biodiversity Institute would therefore like to highlight the facts.

“The information being circulated refers to the ‘arum lily micro frog’ which does not exist. There are, however, two different species of frog, namely the micro frog (Microbatrachella capensis) and the arum lily frog (Hyperolius horstockii). The micro frog is smaller than a fingernail, while the arum lily frog is somewhat larger, growing to about 40 mm in length. It has been reported that the ‘arum lily micro frog’ is in danger because of the sale of arum lilies, but this is not at all correct for either of the frog species.

“The supposed threat to these frogs’ habitat has been cited as one of the main reasons why the public should not buy arum lilies. However, no frog species breeds in the flowers of arum lilies. While the arum lily frog occasionally uses the flowers for shelter, it is not dependant on them. Arum lily frogs breed in wetlands and not in the flowers of the arums. The micro frog is ground-dwelling, breeding in temporary pools, and it does not climb into any flowers.

“Arum lily frogs are very pale and they hide their bright orange feet and legs under their bodies during the day. In this way, the frog is able to use a white background as camouflage against predators and this background is sometimes the white arum flower. They do not use the pollen of the flowers to camouflage themselves, as has been suggested.

“While arum lily frogs are only found in the Western Cape (and a small area of the Eastern Cape), they are not classified as threatened in the 2004 Red Data book. However, it is true that the species is becoming increasingly rare as their habitat is lost to urban development.

Only buy from traders in demarcated areas – not roving hawkers

“While the illegal harvesting of arum lilies will not lead to the extinction of arum lily frogs, the sale of illegally harvested flora at traffic lights is cause for concern. If left unchecked, other illegally harvested plants such as proteas, ericas, and various bulb species may be seen at traffic lights in the future.

“The City does not wish to deter the public from purchasing flowers from hawkers – as long as they are legal retailers. All roving vendors and intersection traders selling flowers are illegal. However, traders selling flowers in demarcated trading bays are legal, and regulated by the City. The City encourages the public to report illegal trading on 021 596 1400/1424.

“The ERM Department is always grateful when residents spread its messages because the need for awareness is so great. Unfortunately, this message has become lost in translation, and we hope that the correct information, as it appears above, will spread in the same manner,” said the City’s Biodiversity Co-ordinator, Clifford Dorse.

“The ERM Department is currently updating its pamphlets on frogs and lilies, and will distribute them widely in an attempt to ensure that the public receives the correct information.”

Local is lekker, in sugarbird terms; a good case for planting more fynbos species.

Betty’s Bay bird update

From Marianne Alexander, a member of the Constantia Valley Garden Club (see her previous rock thrush post):

We had no sooner arrived at Betty’s Bay this weekend when the rock thrushes appeared at the windows. They seemed to know instinctively where to find us, even when we went upstairs!  We thought they only had one youngster, but at dusk – as the sun set and we were enjoying a beer on the upstairs patio – they appeared out of the gloom with two more!

Mum (it appears) keeps tabs on their whereabouts, uttering a deep, throaty chuckle to warn them of danger while Dad does all the hard work – rushing backwards and forwards, dropping the cheese we had on offer into their gaping mouth (see picture above). He is handsome isn’t he, feeding one as another sat chirping on the neighbour’s washing line.

Worried about their cheese intake we offered cook and raw chicken, which was rejected!

Mrs Robin is still about with her single chick but keeps to the undergrowth as  the thrushes are real bullies and chase her and other birds away from any food.

Betty’s Bay Birds

Rather fraught looking mother robin feeds her baby with cheese

Marianne Alexander has a weekend home in Betty’s Bay (where she grows wonderful indigenous plants). She writes:

“Within minutes of arriving at Betty’s Bay a mother robin is at the window asking for cheese. On this visit she brought her baby right onto the stoep and fed it at our feet while we watched.”

“The larger Cape Rock thrushes, above, were not as bold and carefully collected as many pieces of cheese as they could manage in their long beaks and flew off to feed their baby on the near by wall.”

What do your garden birds eat?
