Macolline is a botanical nature reserve 3km from the town centre of Antalaha. Also known as Ambinany, the park covers 10 hectares and has over 600 native and introduced plants and trees with precious and semi-precious species as well as a diverse fauna, including chameleons, butterflies and lemurs.

Macolline Park was founded by Marie Hélène Kam Hyo, a pharmacist in Antalaha. A species of the Clerodendrum family (Lamiaceae) was discovered here in 2002 and and in 2016 formally identified and named Clerodendrum kamhyoae.

While flowering usually begins in April and continues until July, a highlight can be observed at the peak of flowering in May when the trunk of each tree is draped in long elegant clusters of white flowers. Marie Hélène dubbed the plant "Lamariée" ("The Bride").

The Clerodendrum kamhyoa plant has been assigned a preliminary status of “Endangered” by IUCN Red List Categories and Criteria. Conservation efforts at Macolline have significantly lowered its risk of extinction.

In 2008 the park opened as a conservation site including an educational centre offering visitors the opportunity to learn and see the different botanical species along a well-maintained trail including beautiful views of the surrounding landscapes.

Among the different species in the park there are:

Fast-growing woods are often used as firewood and in timber for construction of furniture. One such tree is Intsia which can grow at a rate of one metre per year.

Slow-growing woods: These are hardwoods that take several decades to grow. They are precious woods because they have a high value and are used to build luxurious furniture. Precious woods include palisander, ebony and rosewood. Macolline are collecting and distributing rosewood and palisander seeds and seedlings for replanting initiatives.

Native species: We speak of an indigenous native species when the plant is native to the country in which it is observed but its distribution area does not stop only in this country. That is to say, it can exist naturally in other regions of the planet. For example, one native species at Macolline is Canarium madagascariense which apart from Madagascar, occurs naturally in Mozambique and Tanzania.

Endemic species occur naturally without human intervention and when they only grow or live there. In Madagascar and Macolline endemic species include Ravenala madagascariensis, Clerodendrum kamhyoae, Bamboo lemur and Mouse lemur.

The exotic species: A species introduced (planted) in a country that is not its country of origin, it is said to be exotic. Some exotic species become very invasive and prevent native plants from reproducing.

Lianas: In tropical forests including Macolline, lianas are abundant. They climb along tree trunks or remain free and hanging from branches making it difficult to spot the beginning or the end. Lianas are terrestrial plants that seek light. Liana is a name given to all types of terrestrial or epiphytic climbing plants, capable of clinging to a support.

Epiphytes: These are aerial plants that use other plants as support without being parasitic on their host. As they grow, epiphytes seek more light. It is rainwater or dew that waters them or runs off their support. As for nutrients, they are provided by the humus fixed on the tree. Many epiphytes are orchids, ferns and philodendrons.

Two distinct types of root formations that can be seen in the Macolline forest are stilt roots and foothill roots.

Stilt roots are produced by the trunk or branches and develop in the open air before penetrating the ground. This adaptation allows a better base and elevation above the water (competition for space). In the undergrowth, some trees grow by extending their roots towards the brightest areas (competition for light).

Foothill roots are vertically flattened root expansions, glued to the trunk. Depending on the size and age of the tree, the buttresses can be numerous, reach several meters high and branch out. They allow better fixation and resistance to wind.

Along the Macolline trail, visitors can expect to see:

1. Coffee tree - Coffea arabica

2. Litchi - Litchi sinensis

3. Canarium madagascariense

4. Ficus tiliifolia

5. Mango tree – Mangifera indica & Asplenium nidus (bird’s nest fern)

6. Uapaca sp.

7. Pandanus sp.

8. Bismarckia nobilis

9. Dypsis crinita

10. Phyllarthron antongilensis

11. Jackfruit – Artocarpus heterophyllus

12. Vanilla planifolia

13. Cinnamomum Zeylanicum

A knowledgeable guide explains the different species and their uses in traditional Malagasy medicine and culture.

A canoe ride from behind the park offers visitors a tour of a traditional brick-making facility along the river behind the park.

It is difficult not to spot chameleons when visiting Macolline. Species of chameleons found in the park include Panther chameleon (Furcifer pardalis) and Madagascar pimple-nose chameleon (Calumma nasutum).

Among the introduced non-invasive species is the Vanilla planifolia orchid, which can be seen flowering between September and November. Each flower blossoms for only one day each year and does not produce vanilla beans unless it is pollinated by hand. The best time to see the orchids is in the early morning hours.

The park is open to visitors every day. An information centre and various locally handcrafted souvenirs are for sale at the entrance.
