Distribution of the local form Vohimarina :

Vohimarina, better known by its French name Vohémar, is a city on the northeast coast of Madagascar. With a population of around 15,000, it is one of the larger cities in the Sava region. In colonial times, the town was called Iharana in Malagasy, but this name is now only used for the area surrounding the town. Vohémar has an important harbor and an airport that has not been functioning for a long time. The city can only be reached by land from Ambilobe via the RN5a, which was renovated in 2022. Alternatively, you can fly to Sambava on a very small plane and drive to Vohémar from the south via the RN5a. The people here live mainly from fieldwork and fishing. Rice, cassava and peanuts are grown, and there are also very many zebus in the area.

Panther chameleons are found here in open landscapes between fields and in bushy secondary vegetation. Primary rainforest or dry forest no longer exists near Vohimarina. Rice fields and wide, flat grasslands with bushes and low trees against a mountain backdrop characterize the plains between Vohémar and Daraina. Herds of zebu are everywhere. Somewhat lusher vegetation is present along the rivers, with larger and older trees along narrow strips. South of the local form runs the Fanambana River, which is the boundary with the Sambava local form. Panther chameleons of the Vohémar local form are surprisingly found as far as Loky Manambato near Daraina. There, a good 50 km away, is also the next protected dry forest remnant. This is astonishing mainly because the Manambato River actually separates the two areas. Nevertheless, the panther chameleons look the same in both regions and show hardly any variation.

Appearance of the local form:

The males of Furcifer pardalis here are light green with dark red banding. In contrast to the neighboring local form Sambava the head of the males here is green, not red. Only the eyelids are colored red. The throat region may have red tints in some animals. The animals of the local form Vohémar look extremely similar to the local form Ankarana East despite some distance.

The data given were measured and compiled by us within one year with thermo- and hygrometers in Vohémar. "Average temperature" means that the values of an entire month were calculated to an average value, e.g. all measured minimum values of a month were calculated to an average minimum value for February. This means in plain language that individual peak values of a day can be significantly higher or lower than the average minimum and maximum values. So it is possible that while the average maximum is 29 degrees, it was 33°C or even 35°C on some days of the month.

Vohémar is located directly on the Indian Ocean in a bay, so the climate is very warm all year round. In the rainy season, it is correspondingly scorching hot in Vohémar, temperatures over 30°C in the shade are the rule. Extensive rainfalls and thunderstorms provide a sultry heat like in a steam bath.

During the dry season, on the other hand, it gets really dusty in Vohémar and rain falls only from time to time. Key factors in Vohémar are certainly both the great heat and the dryness during the dry season, which is rather untypical for the east coast.

The UVB data were measured with a Solarmeter 6.5 in spring (April) just after the highest activity time of the chameleons. In each case, the maximum values achievable for the chameleon in the habitat were measured.

Unfortunately, ground temperatures for Vohémar are not yet available.

Habitat:

Panther chameleons live around Vohémar in open landscapes. Vohémar lies directly on the sea, so the soil is a mixture of sand and laterite. Between Vohémar and Loky Manambato there are mainly savannahs with isolated low trees and many bushes distributed in gentle hills. At the edge of the mountains, which become more towards the center of the country, there are a few dry remnant forests and some gallery forests along smaller rivers. Loky Manambato, on the other hand, is a still intact small dry forest. The tree population is rather young and not very high, but there is plenty of strongly branched undergrowth. The soil here is interspersed with rocks and consists almost entirely of laterite.
