Conectividad / Canal de noticias

Los avances en las redes de comunicación que conectan sensores y permiten la recuperación de datos en diversos entornos están revolucionando el trabajo de campo en conservación. Como infraestructura que permite que nuestras herramientas esenciales se comuniquen entre sí incluso en los lugares más remotos, la importancia de la conectividad es fundamental. Independientemente de las soluciones con las que trabajes y de la escala a la que estés sometido, este grupo es el lugar ideal para debatir todo lo relacionado con la conectividad en la conservación, desde cables de fibra óptica hasta LoRa y Swarm.

Citizen science tool for microplastic mapping in underserved regions

Hi everyone, I'm a high school student working on a free citizen science tool for microplastic pollution in underserved regions. The idea is simple: a mobile web app where anyone...

Hi Mykhailo. That citizen science tool seems interesting. But, how do you expect people to detect microplastics (ranging from 1 µm to 5 mm in size)?

Hi Macayle! My assumption is that this is an in-person only event...yes? If there is an option to join remotely or listen in, please do follow up and share with our Community! I would personally love to attend, and I am sure many others would as well! And if there may be any content that is publicized post the event, please do share that as well. :) Sounds like a fantastic initiative -- thank you for sharing! Cheers!

Women in Conservation Forum (WiCF) 2nd March in Nairobi: GoFundMe platform

Hello all, We have set up a GoFundMe platform for Women in Conservation Forum. Our goal is to make the day as open and accessible as possible. We would greatly...

Hello Macayle

It is of great pleasure that there is this opportunity coming to East Africa. I would like to attend this. Do you have any recommendation for funding  a student to attend such a forum? I will share this opportunity with our East Africa WhatsApp group too.

Hi Susan, 

Thank you for your message. 

I apologise, but as we are a non-profit and mostly volunteer-run, we are presently unable to provide funding support to people to travel to Nairobi for the forum. 

Thank you for sharing WiCF with the whatsapp community; that’s lovely of you!

I can write up an official letter of invitation if that would help with a university bursary application, and WiCF attendees will receive a certificate of attendance for the day. 

I have a small invitation flyer; feel free to share this with others who may be interested. 

Kind regards,

Macayle

Thank you! 

Hi Macayle

Are these two different forums; one in Mombasa and other in Nairobi? can you make me understand please?

 

Hi Susan, We are just organising the one – Global Conservation Tech and Drone Forum 2-6 March in Nairobi. Women in Conservation Forum is a one-day forum on 2nd March, part of the wider GCTDF. https://www.gctdf.org/agenda I was merely mentioning the Our Ocean Conference in Mombasa because of its importance in marine conservation.

VHF Frequencies

Hello everybody,I hope this goes into the right group. I'm currently collecting information about the distribution of international vhf frequencies for wildlife tracking. It's a...

5 0

In the U.S., 148-152MHz, 163-165MHz and 216-220MHz are the most commonly used for wildlife tracking.  I think there are some very specific/narrow disallowed segments in those ranges but I've generally relied on tag manufacturers to know to avoid those.   As Matthew mentioned, there are also limits on power output for legal use of these frequencies.

Forest Guard

A Decentralized Edge-AI LoRa Mesh Network for Forest Surveillance

3 4
Hi Mukesh, looks really promissing. happy to discuss.

Hi Mukesh — this is a well-thought-out architecture and the combination of Edge Impulse + Meshtastic is a smart choice for keeping the stack open and maintainable.

A few thoughts from field deployment experience with similar systems in remote African environments:

On the LoRa mesh topology — Meshtastic works well for general mesh but uses a flooding algorithm that can become inefficient as node count grows. For a dense sensor network where you have many nodes but relatively few gateways, consider whether a more structured topology (like a simple star-of-stars with dedicated repeater nodes at higher elevation points) might give you better latency and battery performance. The flooding approach also burns extra TX cycles on every node for every message, which matters if you're trying to squeeze months out of a solar cell.

On power — for permanent solar installations in tropical and savannah environments, the main risk isn't average insolation but multi-day cloud cover during wet season. A 3-5 day battery reserve at minimum operating current is worth designing in explicitly. The BQ25504 MPPT IC is a good choice for harvesting from small cells — it starts up at very low input voltage which matters in low-light conditions.

On acoustic model reliability — gunshot detection in open African bush is harder than in forest because there's less acoustic diffraction and more wind noise. The VM3011 mic you mentioned in other threads handles wind well, but you'll want to train your Edge Impulse model on savannah soundscapes specifically, not just forest recordings. False positive rate from vehicle backfires, thunder, and snapping branches can be high if the training set doesn't include local ambient audio.

On chainsaw detection for illegal logging — this is actually easier than gunshots because of the sustained harmonic signature. If you retrain for this, worth adding accelerometer data as a secondary feature — a chainsaw physically couples vibration into whatever surface it's resting on, which can improve classification confidence.

Happy to discuss deployment architecture further — I've been working on LoRaWAN-based tracking systems and have gone through a lot of these trade-offs in practice.
