Every Borneo (Part of Indonesia or Kalimantan) fruiting season starting on about January until March, i'm always departed to Borneo (Kalimantan) since 2014 to explore, hunting and searching wild fruits to collect the seeds.
I'm collecting wild fruit seeds for my customers, and it's my main occupation and always doing it every year.
And by the way i'm living in Central Java, Indonesia.
In hunting wild fruits, i have visited Pontianak/Sanggau/Sekadau/Putussibau (West Kalimantan), Banjarmasin/Tanjung (South Kalimantan), Pangkalan Bun/Palangkaraya/Sanggau/Murung Raya (Central Kalimantan).
If someone want to search wild fruits in Kalimantan, i'm able and offering a service as a guide.
Rate negotiable, i'm not bringing a car but using public transportations, i suggest you to rent a car or motorcycle.
All you need is following me moving around Kalimantan, cause some species only grows in specific places (For example Willughbeia elmerii, only grows in West Kalimantan and can't be found in East, Central or South Kalimantan).
Planning to depart to Kalimantan island on about middle January from Solo city, Central Java but the flight are from Yogyakarta Airport.
Anyone interested, can contact me.
