TACHIGALI
Ecological Monitoring Infrastructure
TACHIGALI is an ecological monitoring system being developed in Costa Rica to help field observations remain useful long after the moment in which they are recorded.
An observation rarely exists in isolation.
It happens at a particular place and time, under particular conditions, as part of a project or monitoring effort. It may involve an individual organism, another species, a behavior, a resource, an interaction, a habitat or an environmental change.
Much of that context is easily lost.
TACHIGALI is being built to preserve it.
Why TACHIGALI exists
Ecological information is often distributed across notebooks, spreadsheets, photographs, field applications, species lists, databases and the memories of the people doing the work.
Each of these can be useful.
The difficulty appears over time.
A record may survive while the circumstances surrounding it disappear. Observations made by different people become difficult to connect. Taxonomy changes. Projects change hands. Photographs become separated from records. Repeated observations of the same place or individual are treated as unrelated events.
Eventually, information that was collected together becomes fragmented.
TACHIGALI began as an attempt to solve that problem in a real ecological monitoring project.
From records to context
At its simplest, an ecological observation answers a question:
What was observed?
But many of the questions that become interesting later require more context.
Where was it?
When?
Who recorded it?
How was it detected?
What evidence exists?
Was the identification reviewed?
Was this organism seen before?
What habitat was it using?
What was it doing?
Was another organism involved?
Has the site changed?
Does the same pattern appear elsewhere or at another time of year?
TACHIGALI is being designed so that these pieces of information do not have to remain isolated from one another.
The objective is not simply to accumulate records.
It is to preserve the relationships between them.
Current development
TACHIGALI is currently being developed and tested through a real ecological monitoring implementation in Costa Rica.
The system already extends beyond a single field application. Its development includes infrastructure for sites, organisations and monitoring projects; field data capture; taxonomy; media and evidence; review workflows; individual organisms; spatial information; and the movement of data between field devices and the wider system.
Field work also needs to continue when internet access does not.
For that reason, offline capture and later synchronisation are treated as fundamental parts of the system rather than exceptions.
Development is ongoing, and the capabilities described here will continue to change as the system is tested against real field conditions.
Ecological interactions
One of the long-term directions of TACHIGALI is the documentation of interactions.
Species lists are valuable, but ecosystems are not species lists.
A flowering plant visited by a hummingbird, a fungus infecting an insect, a predator consuming prey, an army-ant swarm followed by birds, a fruit removed by a mammal, or two organisms competing for the same resource contain information that disappears when each participant is recorded independently.
These relationships occur across many scales.
An interaction can last seconds.
A phenological pattern can repeat over years.
Changes in habitat may alter relationships across an entire site.
Individual organisms may repeatedly participate in the same network of resources, competitors, parasites, predators or mutualists.
TACHIGALI is intended to grow toward recording and connecting these kinds of relationships without reducing them to a single list of categories.
Time, place and change
Ecological meaning often appears through repetition.
One observation tells us that something occurred.
Repeated observations can begin to tell us when it occurs, where it occurs, whether it changes, and what else changes with it.
Long-term monitoring therefore requires more than storing observations.
It requires maintaining continuity between places, methods, organisms, people and time.
TACHIGALI is being designed around that continuity.
A site should accumulate history.
An individual may accumulate observations.
A project should retain its methods and decisions.
A taxon should remain traceable when its classification changes.
Evidence should remain connected to the record it supports.
Changes should not erase what was understood before them.
Scientific integrity
Ecological databases become less useful when it is impossible to determine where information came from or how it was interpreted.
TACHIGALI is therefore being developed with provenance, review and traceability as part of its structure.
The intention is to distinguish observations from interpretations, original evidence from later decisions, and accepted information from records that still require review.
External biodiversity resources can complement this work rather than being replaced by it.
Platforms such as iNaturalist and eBird are extraordinarily useful for public biodiversity records and occurrence data. TACHIGALI addresses a different problem: preserving the internal ecological context of monitoring work and connecting information that may extend beyond a single occurrence record.
Long-term direction
TACHIGALI began with practical field problems, but its long-term direction is deliberately broader.
The aim is to develop infrastructure capable of connecting observations across organisms, interactions, individuals, sites, projects, space and time.
As those connections accumulate, they may allow questions to be asked that are difficult to answer from isolated records.
How does an interaction change through the year?
Which organisms repeatedly use the same resources?
How does a network change after a disturbance?
Do relationships observed at one site appear at another?
How does the history of an individual intersect with the history of its habitat?
What happens when records collected for different purposes are examined together?
TACHIGALI will never contain a complete representation of an ecosystem.
No database can.
The more useful goal is to preserve enough context that observations made today can participate in questions we have not yet thought to ask.
An evolving system
TACHIGALI is still under active development.
Some components are already being tested in the field. Others remain under development, and some of the larger ideas described here belong to its long-term direction.
That distinction matters.
The project is intended to grow through field use, scientific scrutiny and practical necessity rather than by adding features simply because they are technically possible.
Its architecture is therefore being developed as infrastructure rather than as a fixed application with a final feature list.
Collaboration
TACHIGALI is currently being developed through Neotropic Field Systems in Costa Rica.
We are interested in situations where real ecological work can expose problems that a laboratory specification cannot: biological reserves, long-term monitoring projects, research sites, conservation programmes and other organisations responsible for maintaining ecological information through time.
If your work presents a monitoring problem that TACHIGALI may eventually help solve, we would be interested in learning about it.
