Why would you want to avoid alerting the rangers ?

You don't need high tech for this; elephants leave very obvious tracks and sign. 

Hi Tyler,

Would like to introduce you to Ceres Tags products

• Ceres Tags products come in boxes of 5, 10 and 24. 
• There are some software partners such as Earthranger, Mapipedia and possibly CiboLabs that would be able to assist you with your mapping vegetation requirements
• Ceres Tag does not require any towers, base stations and infrastructure. This allows you to see any movements from the heard outside of their normal herd (boundary alerts), and you will not be disturbing any of the flora and fauna with infrastructure set up. 
• For the timing you are looking at, Ceres Wild pings directly to satellite 24 times a day. For Ceres Trace and Ceres Ranch there are 4 within 24 hours. Taking into consideration, when you set up alert areas, you will get them directly to your phone/laptop via your software of choice
• Ceres Ranch is a reusable tag that has just been launched. Use it on this project, remove the tag and then use the tag on your next project
• The software you choose will assist with the history of your animal movements. Ceres Tag is integrated with 11 software partners and in-development with 18 software partners https://cerestag.com/pages/software-partners
• Understanding it is a short-term project, you would be able to use Ceres Tags products without the additional expense of setting up and removing infrastructure- towers, gateways
• With Ceres Tag, you are purchasing the box of tags and picking a suitable software to deliver the information you require. On average, a box of 10 Ceres Trace Tags, is the same as 1 LoRaWAN tower. 

I just came across this interesting paper in which seismic monotoring of animals like elephants was mentioned. 

This is the study refered to:

Cheers,

Hello Carlos and Chavoux, 

Interesting exchange, thank you! Working on HWC, boh locally on Human-Jaguar coexistence in French Guyana and globally through the ENCOSH platform, it would great to learn more from your initiatives and  experiences!

An opportunity to do so is to join us and contribute to the ENCOSH platform: https://encosh.org/en/

It is a recent international collaborative platform to promote the exchange of knowledge, experiences and ideas among all stakeholders worldwide to better tackling Human-Wildlife coexistence issues. A forum will be very soon included also. 

Your contribution would be meaningful by submitting some of your initiatives to this community. Besides, you could find and make comments on a list of almost 100 extant initiatives used to enhance Human-Wildlife interactions worldwide. 

I remain available if you need further information or guidance. 

All the best 
Tommy Gaillard

This is an awesome thread and very enlightening. Thank you! I started reading this as Oregon recently had an entire pack of wolves poisoned, and I wanted to understand the viewpoints that go into these conversations. Thank you!

Good day Lily.

I stumbled upon this post of yours.
Have you been able to make any advancement on this topic, or get any feedback from anyone?

I have been asked a similar question by a group, looking at early warning systems for large mammals, like elephants, of possible danger situations.

On my side, it is still a very new project, however, my use case has more to do with the trains that kills the elephants, but we also have a use case for early warning systems to recognize poachers and early warning systems to intercept any possible threat.

So if you are in a position, and willing to share any information, I would like to find out more, if there has been any developments regarding this topic aon your side.

Kind regards

Hi,

Generating infrasound is generally energy intensive and expensive.  You can google "infra-subwoofer" and despair at the prices!  But those are for audiophiles.  I came across a fan type speaker design a long time ago that I think can be adapted,  Another possibility is to use pyrotechnics to generate infrasound, but that would not be reusable and I suspect development will be even more of a headache.  An intriguing possibility is to use basically a fogger - - those noisy smoky fumigators -- but built to produce the lower frequency.

You should check out Smart Parks (https://www.smartparks.org/) and Hack the Poacher (https://www.hackthepoacher.com/).

That last paper is a nice overview of different methods, and they have a section on acoustic strategies.
